For both questions I need help with part B, finding the p-value.

For both questions I need help with part B, finding the p-value. Consider the following hypothesis test: Hoiu > 20 Ha: M 29 A

Consider the following hypothesis test: Hoiu > 20 Ha: M 29 A sample of 40 provided a sample mean of 30.4. The population standard deviation is 4. a. Compute the value of the test statistic (to 2 decimals). 2.21 b. What is the p-value (to 4 decimals)? c. At a = .01, what is your conclusion? p-value is greater than 0.01, do not reject Ho d. What is the rejection rule using the critical value? Reject H o if z is greater than or equal to 2.33 V What is your conclusion? The test statistic is less than the critical value. Do not reject
