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.
Q4) Data of 100 students' score was recorded. The arithmetic mean and standard deviation were 60 and 15 respectively.

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.

Four-year-olds in China average 3 unsupervised hours per day. Most of the unsupervised children live in rural areas, considered safe. Suppose that the amount of unsupervised time is normally distributed with standard deviation 0.5 . A Chinese 4-year-old is randomly selected from a rural area. We are interested in the amount of time the child spends alone per day. In each appropriate box you are to enter either a rational number in "p/q" format or a decimal value accurate to the nearest 0.01 a. (3%) In words, the random variable X in which we are interested is defined by X = (pick one) b. (3%) Find the probability that the child spends less than one hour per day unsupervised. P(X 10) = d. (3%) The 70th percentile of the distribution of unsupervised time is given by P(X < = 0.70 .
