Suppose you wish to determine if the mean IQ of students on a certain campus is different from the mean IQ in the general population, 100. To conduct this study, you obtain a simple random sample of 60 students on this campus, administer an IQ test, and record the results. The mean IQ of the sample of 60 students is found to be 107.2 with a standard deviation of 11.8. Complete parts (a) through (c) below. Click the icon to view the t-distribution table.

Suppose you wish to determine if the mean IQ of students on a certain campus is different from the mean IQ in the general population, 100. To conduct this study,
you obtain a simple random sample of 60 students on this campus, administer an IQ test, and record the results. The mean IQ of the sample of 60 students is
found to be 107.2 with a standard deviation of 11.8. Complete parts (a) through (c) below.
Click the icon to view the t-distribution table.
(a) Construct a hypothesis test Hg: u= Ho versus H,: µ# Ho for Ho = 103, 104, 105, 106, 107, 108, 109, 110, 111, and 112 at a= 0.05 level of significance.
