Create a side-by-side boxplot. Based on the boxplot, is there evidence that the null hypothesis will be rejected? O No, because each boxplot has the same distribution indicating an equal or similar mean. O Yes, because each boxplot has the same distribution indicating an equal or similar mean. O Yes, because the boxplot for the group of sedentary men appears to show higher HBE levels compared to the boxplot for the other two groups indicating that the means are different across groups. O No, because the boxplot for the group of sedentary men appears to show higher HBE levels compared to the boxplot for the other two groups indicating that the means are different across groups.

Human beta-endorphin (HBE) is a hormone secreted by the pituitary gland under conditions of stress. An exercise physiologist measured the resting (unstressed) blood concentration of HBE in three groups of men: 15 who had just entered a physical fitness program at least 3 months ago, 15 who had been jogging regularly for some time, and 15 sedentary men. The HBE levels (pg/ml) are shown in the table below.
