Question 10: give the conclusion.


Extracted text: The mean of a population is assumed to be 75. However data suggests the mean can be less than 75. A sample of size 100 from the population is considered. Assume a calculated sample mean of 60 and a standard deviation of 10. At the 1% significance level we will determine if the null hypothesis should be rejected. Give the null and alternative hypothesis.


Extracted text: Give the conclusion. O Reject the null since the test statistic is in the rejection region and the p value is less than the significance. Reject the null since the test statistic is in the rejection region and the p -value is larger than the significance. O Fail to reject the null since the test statistic is not in the rejection region and the p-value is less than the significance.. Fail to reject the null since the test statistic is not in the rejection region and the p-value is larger than the significance.
