Suppose the director of a college obtains a simple random sample of 42 students from that country and finds the mean IQ is 104.4 with a standard deviation of 13.7. Complete parts (a) through (d) below. V A. The director is testing if the sample provided sufficient evidence that the population mean IQ score is actually greater than 101. O B. The director is testing if the sample provided sufficient evidence that the population mean IQ score is actually not equal to 101. O C. The director is testing if the sample provided sufficient evidence that the population mean IQ score is actually equal to 101. O D. The director is testing if the sample provided sufficient evidence that the population mean IQ score is actually not greater than 101. Find the test statistic for this hypothesis test. 1.61 (Round to two decimal places as needed.) Find the P-value for this hypothesis test. (Round to three decimal places as needed.)
