A random sample of 100 students is taken from a larger population of students in a multi-lecture course and the sample mean (average) of their final grades is found to be 62.25. Suppose it is known that the population standard deviation is 3.2. I need to make a 92% confidence interval. Which of the following statements is most correct?

a.

The test is not significant at the 1% significance level because 62.75 is inside the confidence interval you created.

b.

The test is not significant at the 1% significance level because 63.25 is inside the confidence interval you created.

c.

The test is significant at the 1% significance level because 62.75 is outside the confidence interval you created.

d.

The test is significant at the 1% significance level because 62.75 is inside the confidence interval you created.
