Suppose the mean IQ score of people in a certain country is 101. Suppose the director of a college obtains a simple random sample of 43 students from that country and finds the mean IQ is 104.6 with a
standard deviation of 13.3. Complete parts (a) through (d) below.
(a) Consider the hypotheses Ho: 101 versus H₁: > 101. Explain what the director is testing Perform the test at the a=0.01 level of significance. Write a conclusion for the test
Explain what the director is testing. Choose the correct answer below

OC. The director is testing if the sample provided sufficient evidence that the population mean IQ score is actually greater than 101.
OD. The director is testing if the sample provided sufficient evidiace that the population mean IQ score is actually not equal to 101
Find the test statistic for this hypothesis test.
(Round to two decimal places as needed.)
Find the P-value for this hypothesis test
(Round to three decimal places as needed)
Write a conclusion for the test. Choose the correct answer below.
