Perform the 7-step procedure of Hypothesis Testing. Use z or t test 1.) It is claimed that the average performance of newly graduated nurses from the recent board exam was 92%.Would you agree to this claim if a random sample of 100 nurses showed an average of 95% with a standard deviation of 15%? (use a=0.05) 2.) Data from a certain hospital shows that the average normal body temperature of 25 healthy adults is 98.2 OF with a standard deviation of 0.62 °F. Based on these data test the claim that the mean normal body temperature of adults is in fact equal to 98.6 °F at 0.01 level of significance.
