A researcher believes that the so-called “sugar high” is not real. He gathered 30 adolescents and recorded their activity level in the scale of 0 – 100 (0 = not active and 100 = super active). First, he recorded participants’ activity level before they consumed candy. After recording their pre-sugar activity level, the researcher gave out 5 Snickers bars to participants. Then, he recorded their post-sugar activity level. The average difference between post-sugar and pre-sugar activity level is 50 (i.e., the activity levels are higher after sugar than prior to it) with a standard deviation of 10.
A). Complete test statistic and critical values
B). Conclusion
5.33 Refer to Exercise 5.27 and calculate the covariance between X and Y.
Researchers examined bone strength by collecting 10 cadaveric femurs from subjects in each of three age groups: young (19–49 years), middle-aged (50–69 years), and elderly (70 years or older). One of the outcome measures was the force in Newtons required to fracture the bone. At α = 0.05, test the claim that the bone strengths differ among the age groups.
