Confidence intervals and p-values

 Confidence intervals and p-values are commonly used in business  decision making.  Two  business journals/articles will be provided that have used confidence intervals  and/or p-values.  For each journal (or article), describe:

1. the problem statement
2. the parameter(s) of interest
3. 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.

The two articles will be provided to the winning bidder. Thanks.
