Re/App 6 – Discrete Probability Distributions
The data attached is from observations of a supermarket “self-checkout” line at random times of day for 25 selected days, for a total of 75 observations. A data value of 1 means there was 1 person in line, a data value of 2 means there were 2 people in line, etc.
In a microsoft word document answer the following questions about the data (data is attached as a file):
(REQUIRED) Answer the following questions about the data:.
(a) What type of data is this? That is, is it: Qualitative Nominal, Qualitative Ordinal, Quantitative Discrete, or Quantitative Continuous data?
(b) Explain WHY you say it is that type. (2 points total for Question 1)
What is the probability P(x > 2)? Express the probability as a decimal, rounded to three places. (2 points)
Find P(x is no more than 12). Express the probability as a decimal, rounded to three places. (2 points)
Does the probability in Question 3 indicate that it was an unusual event? Look up the concept of an unusual event in the textbook, if necessary, before answering! Explain your answer in a full sentence. Be sure you are specific about the value of the probability in Question 3 in comparison to the criterion for an unusual event. (2 points)
In your opinion, does the store need more checkout lanes? Cite specific probabilities from your distribution to justify your written answer; do not just answer yes/no. (2 points)
