Can you correct my test and give me a step-by-step explanation of what I did wrong, as well as why and how?

Complete the following:
Research applications of logarithmic functions as mathematical models. Some ideas include but are not limited to: pH (acidity of solutions), intensity of sound (decibels), brightness of stars, human memory, progress over time in a sport, and profit over time. Choose an area of interest from above or provide one of your own, and explain how logarithmic functions are used.
Provide at least one example. The initial post of your discovery should be at least 250–500 words in length. Use current APA format to cite your sources (e.g., from library books, textbooks, and the Web). Your post must contain some of your own thoughts and reactions, in addition to any citations you make.

Pick ONE of the problems from this collection “Advanced Functions Questions” that has not already been solved. Pretend that you are tutoring someone who has never seen these problems before and give a detailed demonstration of its solution.
Please pay attention to spelling and grammar. These skills are most important in about 80% of college courses that require written papers. Good writing skills will also reflect more positively on your status as a college student and graduate.
The math problem that needs to be solved is in the photo attached and the answer is aswell

I have 10 values and I need box and whisker plot with labels and answer the following questions : Explain what each quartile is on your box and whisker plot (label). That is what does each of the numbers on the box and whisker plot represent in your experiment. Don’t just list the numbers but instead explain what they mean. ie. what does it mean that XX is the Q1 (25%)? You could write 25% of all less than __, 50% of all are… Celery-2.99 Onion-2.99 Grape-2.99 Collards-1.29 Kale-1.29 Cucumber-1.29 Potatoe-1.99 Broccolini-2.99 Mushroom-3.99 Rapini2.99

Purpose
The purpose of this project is to assess your ability to:
Collect and display data.
Use Excel.
Calculate and interpret expected value.
Calculate the mean, media, and mode of data sets.
Determine whether data sets are normally distributed.
Apply the Central Limit Theorem.
Summarize and report findings.
Overview
This module you will turn in the third part of Project 2. This project consists of three parts.
Project 2-1: Identify the Distribution of a Sample – due in Module 9
Project 2-2: Find A Sampling Distribution of Sample Means – due in Module 10
Project 2-3: Final Submission – due in Module 11
Data that follows a normal distribution pattern is predictable and can be used to draw conclusions. However, many data sets do not follow a normal distribution pattern, and a small sample may not follow the normal distribution even if it comes from a normally distributed population. The Central Limit Theorem tells us that the distribution of sample means will not only be normally distributed, but also, if we have enough samples, the sampling distribution will have a mean that is approximately the same as 𝜇, and a standard deviation that is close to 𝜎𝑛.
To see this, let’s continue the experiment using sets of randomly generated integers.
Action Items
Open your saved Excel file as submitted for Part 2.
Review your gradebook feedback and make any required corrections to Parts 1 or 2.
Complete the tab labeled “Part 3 – Calculate” by using Excel formulas to do the following:Calculate the mean and standard deviation for each of the 4 data sets from Parts 1 and 2.
Calculate the expected standard deviation of the sampling distribution of the sample means.Note, you may either calculate these directly on this tab using cell references, or calculate these using formulas on your original sheets and copy/paste the values into the designated area of the calculation sheet.
Explain how your graphs tables and calculations of the mean and standard deviations relate to the Central Limit Theorem.

attatched is a sample of what it should look like and also a outline to add answers. thanks so much in advance

As an aspiring educator, you might be teaching the concepts from Weeks 2 and 3 to students. This assignment will give you an opportunity to think about what that situation might look like as you create a resource for a future teacher. The future teacher might be you or someone else.
Review the content, your notes, and your Journal Reflection Questions from Weeks 2 and 3. Your reflection answers will help you complete this assignment.
Identify the ideas that would be important for your future self or another future teacher to remember.
Choose 1 of the following formats to use for the resource you’re creating:
A 10- to 12-slide Microsoft PowerPoint presentation with speaker notes
Create your resource. In your resource:
Identify the topic(s).
From your perspective, develop the important student learning outcomes for the mathematical concepts from Weeks 2 and 3.
Include any rules and definitions that are important for students to learn.
Discuss strategies your future self or another future teacher could consider when developing ideas for teaching the concepts.
Share parts of your reflections that were meaningful to you and discuss why. For example, you might include observations of your own learning, the use of the learning tools, things that were surprising to you, connections you made, or any other topics that you want your future self or another future teacher to remember.
Create qualitative and quantitative explanations of one, two, and three-dimensional space
Just some quick notes about the Summative Assessment. What this assignment is looking for is a summary of the key vocabulary words and their definitions as well as the major concepts, rules, and processes that you might be expected to teach. It is completely acceptable to research those skills that you are not comfortable with, just be careful to cite your resources properly, using APA format.
The idea is that you will take the most important ideas from this chapter and present them. Part of this presentation will be as you might present it to students, however, there are two other parts that students sometimes struggle with.
One of these answers the question: “What specific strategies, tools, manipulatives, and models will you use to teach fractions?” Here, the expectation is that you will describe strategies that are specific to the teaching of fraction sense (this may be in addition to the general strategies that you might use to teach anything, such as, “Keep the lesson engaging.” I strongly recommend that you make one specific slide that lists the models, representations, or other strategies that you might use to teach this topic.
The other is your reflection. Write a few sentences about how you learned numeracy. Was it a positive or negative experience for you? How will this influence the way you plan to teach your students? I strongly recommend that you make one specific slide that lists explains what you learned about fraction sense, how you learned it, and how that will impact the way you will teach it.
A list of references may be needed. Make sure to list any reference where:
You looked up or copied a definition
You used to help you learn a concept
You copied an image or picture.
Be sure to refer to the APA style manual or Citation Generator for assistance with this.

Using the Clinical Trial on breast cancer dataset. Perform a Kaplan-Meier Analysis or the Log-Rank Test to determine the survival curve for the breast cancer survivors. H0 The risk of 50% of the participants dying from breast cancer will occur within five years. (Null Hypothesis) H1 The risk of 50% of the participants dying from breast cancer does not occur within five years. (Alternative Hypothesis) Ensure to submit the following requirements for the assignment: Review the analysis from the standpoint of how many patients survive over the seven-year time period that the clinical trial covered. Present your findings as a Survival Time chart in a Word document, with a title page, introduction explaining why you would conduct a survival analysis, a discussion where you interpret the meaning of the survival analysis, and a conclusion should be included. Your submission should be 2-3 pages to discuss and display your findings. Provide support for your statements with in-text citations from a minimum of two scholarly, peer-reviewed articles. One of these sources may be from the class readings, textbook, or lectures, but the others must be external. The Saudi Digital Library is a good place to find these sources and should be your primary resource for conducting research. Follow APA 7th edition and Saudi Electronic University writing standards.

What you will be turning in:
