c. After conducting the appropriate significance test, the test statistic was found to be -1.26. Therefore, the conclusion for the test is: Reject Ho, because p-value is less than 0.05 Fail to reject H1 , because -1.26 falls outside the critical region Reject Ho, because -1.26 falls within the critical region Fail to reject Ho, because p-value is greater than 0.05

An instructor of statistics believes that the mean score of students on the first statistics test is 65 out of 100 marks. He randomly samples 10 statistics student scores and obtains the average scores as 63 with a standard deviation of 5.01. He performs a hypothesis test to know whether the mean score of students is varied from 65 by using a 5% level of significance.
