Deidre does not think exercise makes a difference in weight loss when trying to lose weight. She gets two random samples of the
amount of weight lost between those with exercise and those without. The top graph shows the amount of weight lost for those with exercise and the bottom graph shows the amount of weight lost for those without exercise. Which statement correctly compares the distributions? A) Those who did not exercise lost 5 more pounds than those who did exercise.
B) Those who did not exercise lost 2 fewer pounds than those who did exercise.
C) Those who exercised had more consistent weight loss than those who did not exercise.
D) On average, those who exercised lost about 4 more pounds than those who did not exercise.
Step-by-step explanation:Since the medians are approximately the same they lost on average around the same amount regardless of exercise. Notice that the range of those with exercise is smaller though so they were more consistent in the amount of weight lost.
Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude; in terms of energy, each whole number increase corresponds to an increase of about 31.6 times the amount of energy released, and each increase of 0.2 corresponds to approximately a doubling of the energy released.
4 Americans can arrange themselves in 4! ways.similarly ,3 Frenchmen can arrange themselves in 3! ways.3 Englishmen can arrange themselves in 3! ways.now these 3 groups of same nationality people can be arranged among themselves in 3! ways.so total number of ways = 3!4!3!3!
