Question 7 (0.5 points) Consider the following hypotheses Ho: mean 16 H1: mean 16 A test is performed with a sample of size 100. The sample mean was 6.23 and the population standard deviation is 60. Assume that the population is approximately normal. Use the TI-84 PLUS calculator to compute the P-value Round your answer to four decimal places (for example: 0.0138) Write only a number as your answer Your Answer Question 8 (0.5 points Consider the following hypotheses Ho: mean 38 H1: mean 38 A test is performed with a sample of size 144. The sample mean was 49.8 and the popuation standard deviation is 84. Assume that the population is approximately normal. Use the TI-84 PLUS calculator to compute the P-value Round your answer to four decimal places (for example: 0.0138) Write only a number as your answer Your Answer:
