We would like to test whether the population mean is less than 40. Suppose that a hypothesis test is conducted to determine if the mean of the population has decreased. Describe what a Type Il error would mean for this example. Select one: O a. Reject Ho when the population mean has decreased. O b. Do not reject Ho when the population mean has not decreased. O c. Reject Ho when the population mean has not decreased. O d. Do not reject Ho when the population mean has decreased.

We would like to test whether the population mean is less than 40. Suppose that a hypothesis test is conducted to determine if the mean of the population has decreased. Describe what a Type II error would mean for this example. Select one: - a. ☐ Reject \( H_0 \) when the population mean has decreased. - b. ☐ Do not reject \( H_0 \) when the population mean has not decreased. - c. ☐ Reject \( H_0 \) when the population mean has not decreased. - d. ☐ Do not reject \( H_0 \) when the population mean has decreased.
