C8 05 V2: 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 6275. Suppose it is known that the population standard deviation is 33 You wish to determine whether the average grade for the population differs from 62.50. use R to get the needed Z critical value and then create a 95% Z confidence interval for the average final grade for the population by hand. Choose the correct statement below C) The test is significant at the 5% significance level because 6250 is inside the confidence interval pu created. C) The test is not significant at the 5% significance level because 62.60 is inside the confidence interval you created. C) The test is significant at the 5% significance level because 6250 is outside the confidence interval pu created. C) The test is not significant at the 5% significance level because 6275 is inside the confidence interval you created.
