Confidence intervals and p-values are commonly used in business decision making.

Confidence intervals and p-values are commonly used in business decision making. Using the CSU-Global Library, identify at least two business journals (or articles) that have used confidence intervals and/or p-values. For each journal (or article), describe:
the problem statement
the parameter(s) of interest
the conclusion and/or decision.
In addition, state the sample size. If they are using a confidence interval, state the confidence level and margin of error. If they are using the p-value, state the hypotheses, p-value, and level of significance.
