Explain one sample Z test for p-value approach.

Find out the test statistic P-value, and critical value, and state the final conclusion. The mean IQ score of statistic professors is less than 120. Sample data: n = 46. Suppose that = 17, and the significance level is = 0.05.

Compute the test statistic. (Round to the nearest hundredth)

Find the P-value. (Round to four decimal places)

Find the critical value. (Round to the nearest thousandth)
Choose the final conclusion

A. There is enough evidence to support claim
B. There is insufficient evident to support claim
