A simple random sample of 25 math students resulted in a mean IQ of 113.5 with a
standard deviation of 12.5 Use a 0.05 significance level to test a claim that math students have a
mean IQ greater than 110. [Note: Assume the population standard deviation is unknown.]
a. Clearly identify and state the null hypothesis Ho and the alternative hypothesis H1.
b. Determine the critical value(s) and the value of the appropriate test statistic (to nearest
0.001). [Note: Table A-3 might be helpful for critical value(s).]
