Beyond the Numbers 1. One and Done
A sample of n = 75 UK students is taken by the Kentucky Kernel, and each one is asked, "Does
knowing that many of the basketball players Kentucky recruits will go pro after one year affect
your sense of attachment to the team?" Suppose 60% in your sample said, "Yes, it does affect my
attachment." Is it safe for the Kernel to report that a majority of all UK students are likely to feel
that way? Decide between H:p s 0.50 and H:p> 0.50. Assume a Type I error rate of a = 0.05.
a. Report the standard score, the p-value, and state what your decision is.
i. z = 0.60; p-value = 0.420; reject the null.
ii. z= 1.73; p-value = 0.042; reject the null.
iii. z=0.60; p-value = 0.420; fail to reject the null.
iv. z= 1.73; p-value = 0.042; fail to reject the null.
