  1. PROJECT #4  (FOR LESSON 6)

    Perform a hypothesis test for the data you collected for P#3.  Be sure to state the claim, null hypothesis, and alternative hypothesis (8 points).  Choose a significance level such as 0.025 (2 points), give your sample statistic (5 points), and compute the standard error (5 points).  Compute the p-value and formulate an initial conclusion (either reject or support H0) (10 points). Be sure to write a final conclusion as an interpretive sentence that states whether the claim was supported or not (10 points).

    Do all work in an EXCEL workbook and submit electronically via the P#4 link.
