A researcher assesses the level of a particular hormone in the blood in five patients before and after they begin taking a hormone Patient Before After treatment program. Results for the five are shown to the right. Using the 0.05 significance level, was there a significant change in the level 0.17 0. 15 of this hormone? Complete parts (a) through (c). 0.22 0.22 0.18 0.14 0.23 0.20 0.19 0. 16 Click here to view page 1 of the cutoff scores. Click here to view page 2 of the cutoff scores. O A. The mean of the differences of the level of the hormone after the treatment minus the level of the hormone before the treatment is different from zero. B. The mean of the differences of the level of the hormone after the treatment minus the level of the hormone before the treatment is zero. O C. The mean of the differences of the level of the hormone after the treatment minus the level of the hormone before the treatment is greater than zero. What is the research hypothesis? A. The mean of the differences of the level of the hormone after the treatment minus the level of the hormone before the treatment is different from zero. O B. The mean of the differences of the level of the hormone after the treatment minus the level of the hormone before the treatment is not greater than zero. O C. The mean of the differences of the level of the hormone after the treatment minus the level of the hormone before the treatment is not less than zero. Determine the cutoff sample score(s).
