Find the critical value:

Determine the test statistic t: t=

What is the conclustion

For the following claim, find the null and alternative hypotheses, test statistic, critical value, and draw a conclusion. Assume that a simple random sample has been selected from a normally distributed population. Answer parts a-d. Claim: The mean IQ score of statistics professors is less than 122. Sample data: n = 21, x = 121, s = 15. The significance level is = 0.05. Click the icon to view a table of critical t-values. a. Choose the correct null hypothesis (Ho) and alternative hypothesis (H).
