Consider the following hypotheses:

H₀: 84.7

A sample of 42 observations yields a sample mean of 85.7. Assume that the sample is drawn from a normal population with a known population standard deviation of 5.7. Use Table 1.

Calculate the p-value. (Round \"z-value\" to 2 decimal places and final answer to 4 decimal places.)

Calculate the p-value if the above sample mean was based on a sample of 100 observations. (Round \"z-value\" to 2 decimal places and final answer to 4 decimal places.)
