1. High blood pressure is a leading cause of strokes. Medical researchers are constantly seeking ways to treat patients suffering from this condition. A specialist in hypertension
claims that regular aerobic exercise can reduce high blood pressure just as successfully as
drugs, with none of the adverse side effects. To test the claim, 50 patients who suffer
from high blood pressure were chosen to participate in an experiment. For 60 days, half
the sample exercised three times per week for one hour; the other half took the standard
medication. The percentage reduction in blood pressure was recorded for each individual
the resulting data are shown in the table below
Exercise
Medication
X = 14.31 X, =13.28
S, =1.63
S, =1.82
Can we conclude at the 1% significance level that exercise is at least as effective as
medication in reducing hypertension?​

Susie buys two goods - rounds of golf and massages. suppose that the price of a round of golf is $20, and the price of a massage is $30. in a typical week susie will play two rounds of golf, getting 20 units of satisfaction from the second round. she normally buys three massages each week, with the third giving her 30 units of satisfaction. if she were to buy a fourth massage in a week, it would give her 20 units of satisfaction. if the price of massages is reduced to $15, which of the following outcomes might we expect to occur? a) susie would leave her consumption choices unchanged because of diminishing marginal utility in the consumption of massages. b) susie would buy more massages and more rounds of golf, as predicted by the substituion effect. c) susie would buy more massages and fewer rounds of golf, as predicted by the substitution effect. d) susie would buy more massage and fewer rounds of golf, as predicted by income effect.
