3. A researcher, in responding to a request for proposal to conduct a national knowledge, attitudesand practices (KAP) survey on disaster preparedness in a Caribbean Island, suggests the use of asimple random sample. The last survey conducted on the subject in the country, took place fiveyears earlier. At that time, 35% of the population had a satisfactory or better score on disasterpreparedness.a. What sample size should the researcher suggest if there is a required precision of +2.5percent on the proportion of persons with at least a satisfactory score on disasterpreparedness. Assume a negligible sampling fraction (f)b. The researcher was subsequently instructed not to ignore f and use a population of 108,000.What is the new sample size given the same level of precision used in a)

a. Report the two sample means, and state which group had the higher sample mean systolic blood pressure. Refer to the technology output in accompanying figure (A). b. Refer to the technology output given in figure (A) to test the hypothesis that the mean systolic blood pressures for men and women are not equal, using a significance level of 0.05. Although the distribution of blood pressures in the population are right-skewed, the sample size is large enough to use t-tests. Choose from figures (B), (C), and (D) for your t- and p-values. Click the icon to view the technology outputs. a. The sample mean for the women was (Type an integer or a decimal. Do not round,) The sample mean for the men was (Type an integer or a decimal.
