A new variety of pearl millet is expected to provide an increased yield over the variety presently in use which is about 52 bushels per acre. The new variety of millet produced an average yield of 54 bushels per acre with a standard deviation of 12.2 bushels based on 40 one-acre yields. The value of the test statistic for testing the hypotheses that the new variety will increase yield has been found to be 1.04. Is the value of the test statistic likely, assuming that the null hypothesis is true?

Since the test statistic is less than one standard deviation from the mean, it is a highly likely event, assuming H0 is true.

Since the test statistic is between one and two standard deviations from the mean, it is a somewhat likely event, assuming H0 is true.

Since the test statistic is between two and three standard deviations from the mean, it is a somewhat unlikely event, assuming H0 is true.

Since the test statistic is more than three standard deviations from the mean, it is a highly unlikely event, assuming H0 is true.
