They then administer the drug to the participants, wait 30 minutes, and measure their cholesterol levels again. μ1 represents the average cholesterol level before the drug, μ2 represents the average cholesterol level after, and μd represents the average difference between before and after. Test at a significance level of .05. b) Suppose that after analyzing the data, we end up with a P-value of .062. What is the appropriate conclusion? Group of answer choices Fail to reject H0, there is sufficient evidence to show that the drug lowers cholesterol Fail to reject H0, there is insufficient evidence to show that the drug lowers cholesterol Reject H0, there is sufficient evidence to show that the drug lowers cholesterol Reject H0, there is insufficient evidence to show that the drug…

A particular series of consumer price index covers five groups of items. Between 1980 and 1985 the index rose from 180 toʻ225. Over the same period the price index numbers of the groups changed as follows : Food from 198 to 252; clothing from 185 to 205; fuel and lighting from 175 to 195; miscellaneous from 138 to 212; house rent remained unchanged at 150. Given that weights of the clothing, rent and fuel and lighting are equal, determine the weigh s for indi- vidual groups of items.
