Part A
Computing the Z-test Statistic The State College is evaluating a new English composition course for freshmen. A random sample of n = 25 freshmen is selected from the State College. All 25 students are placed in the new English composition course during their first semester. One year later, a writing sample is obtained for each student and their writing samples are graded using a standardized evaluation technique. The average score for the sample is M= 76. For the general population of the State College, writing scores form a normal distribution with a mean = 70 and a standard deviation = 20. Please calculate the appropriate hypothesis test using all four steps?
When performing a hypothesis test to decide whether a predictor variable is useful to make predictions, you observe that p>a. What does this mean? Reject HO: The predictor is useful to make predictions Reject HO: The predictor is not useful to make predictions O Do not reject HO: The predictor is useful to make prediction O Do not reject HO: The predictor is not useful to make predictions
