During a blood-donor program conducted during finals week for college students, a blood-pressure reading is taken first, revealing that out of 300 donors, 43 have hypertension. All answers to three places after the decimal. 1)Assuming our sample of donors is among the most typical 99.9% of such samples, the true proportion of college students with hypertension during finals week is between____and____. 2)Covering the worst-case scenario, how many donors must we examine in order to be 95% confident that we have the margin of error as small as 0.01? 3)Using a prior estimate of 15% of college-age students having hypertension, how many donors must we examine in order to be 99% confident that we have the margin of error as small as 0.01?
Suppose that average male weight in the US is 175 pounds with a standard deviation of 25 pounds. Suppose you randomly select 1,000 male Americans and ask their weight, and average the 1,000 numbers to compute a sample mean X. a) What does the law of large numbers tell you about X, the average of the 1,000? Be precise in your answer using about 1 to 3 sentences.
DO The one-sample -statistic for a test of Ho: 4 = 42 versus H, : I < 42 based on n = 15 observations has the value § 1 = - 1.343, where Ho and H are the null and alternative hypotheses, respectively. The sample size is denoted by n. cmillan Use this 1-table to determine which two P-values bracket the P-value of the test. Report your answers in decimal form as © Ma listed in the t-table.
