In a survey of 3058 adults aged 57 through 85 years, it was found that 83.9% of them used at least one prescription medication. Complete parts (a) through (c) below. How many of the 3058 subjects used at least one prescription medication? b:Suppose you have already conducted a one-tailed hypothesis test at a significance level of 0.05. Use a suitable confidence interval to construct a corresponding confidence interval estimate of the percentage of adults aged 57 through 85 years who use at least one prescription medication c. Does it seem reasonable to conclude that the true percentage is greater than 75%?
