Suppose the director of a college obtains a simple random sample of 45 students from that country and finds the mean IQ is 103.7 with a standard deviation of 13.5. Complete parts a and b. a) Consider the hypotheses Ho: H = 103 versus H1: u > 103. Explain what the director is testing. Perform the test at the a = 0.05 level of significance. Write a conclusion for the test. Explain what the director is testing. Choose the correct answer below. O A. The director is testing if the sample provided sufficient evidence that the population mean IQ score is actually equal to 103. O B. The director is testing if the sample provided sufficient evidence that the population mean IQ score is actually not equal to 103. O C. The director is testing if the sample provided sufficient evidence that the population mean IQ score is actually less than 103. D. The director is testing if the sample provided sufficient evidence that the population mean IQ score is actually greater than 103. Perform the test at the a = 0.05 level of significance.
