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 greater than 135. Sample data:n=12, x= 136, s 13. The significance level is a=0.05.

b. Determine the test statistic t. t= -2.062 (Round to three decimal places as needed.) c. Find the critical value using a t-distribution table. The critical value is -1.746. (Round to three decimal places as needed.) -- d. What is the conclusion? O A. Fail to reject the null hypothesis and support the claim that u <116. O B. Reject the null hypothesis and do not support the claim that u <116, O C. Fail to reject the null hypothesis and do not support the claim that u<116. O D. Reject the null hypothesis and support the claim that u< 116.
