Consider the following hypothesis test: Ho: µ 20 Ha: µ < 20 A sample of 50 provided a sample mean of 19.4. The population standard deviation is 2. a. Compute the value of the test statistic (to 2 decimals). If your answer is negative, use minus "-" sign b. What is the p-value (to 3 decimals)? C. Using a = .05, can it be concluded that the population mean is less than 20? Select v

Consider the following hypothesis test: Ho: µ2 20 Ha: µ < 20 A sample of 50 provided a sample mean of 19.4. The population standard deviation is 2. a. Compute the value of the test statistic (to 2 decimals). If your answer is negative, use minus "-" sign b. What is the p-value (to 3 decimals)? C. Using a = .05, can it be concluded that the population mean is less than 20? Select v d. Using a = .05, what is the critical value for the test statistic? If your answer is negative, use minus "-" sign e. State the rejection rule: Reject Ho if z is select v the critical value. f. Using a = .05, can it be concluded that the population mean is less than 20? Select v
