H0: ? ? 76.7 A sample of 41 observations yields a sample mean of 78.0. Assume that the sample is drawn from a normal population with a known population standard deviation of 4.4. Use Table 1. Calculate the p-value if the above sample mean was based on a sample of 148 observations.(Round \"z\" value to 2 decimal places.) H0: ? ? 76.7 HA: ? > 76.7 Solution Do not reject H0 since the p-value is smaller than ?..
