Question

18) A hypothesis test was performed on a normal population with a supposed mean of 25. For the graphic to the right determine a. The null and alternate hypothesis b. The tail type c. The significance level d. Give a range of values for z which, if the test score falls in this range, will result in rejecting the null hypothesis.
