Do the percentage of positive Covid cases resulting in serious symptoms differ between sexes? nm = 700 random males who had just testedpositive for Covid were selected. Of these, xm = 226 wound up having serious symptoms. nf =600 random females who had just tested positivefor Covid were selected. Of these, xf = 150 wound up having serious symptoms. Suppose Pm is the true proportion of males testing positive forCovid who wind up having serious symptoms. Suppose pf is the true proportion females testing positive for Covid who wind up having serioussymptoms. Pm and pf are unknown and we will examine relations between them based upon these samples. Let pmhat be the sampleproportion of selected males who wind up having serious symptoms. Let pfhat be the sample proportion of selected females who wind up havingserious symptoms. f) Calculate an unbiased point estimate of Pfg) Calculate an unbiased point estimate of Pm - Pfh)Based on this data, calculate a 94% classical confidence interval for Pm-Pf.i. How long is the 94% classical confidence interval for Pm - Pf calculated above?

A pharmaceutical company claims that its new drug reduces systolic blood pressure. The systolic blood pressure (in millimeters of mercury) for nine patients before taking the new drug and 22 hours after taking the drug are shown in the table below. Using this data, find the 90%90% confidence interval for the true difference in blood pressure for each patient after taking the new drug. Assume that the blood pressures are normally distributed for the population of patients both before and after taking the new drug.
