(Ch8) In a large economics class, the professor announced that the scores of a recent exam were normally distributed from 51 to 87. Using the Empirical Rule on µ ± 3σ to estimate σ (that is, σ=[upper limit-lower limit]/6), how many students would you need to sample in order to construct a 90 percent confidence interval of the population mean score, with an allowable error of ±2? (Hint: use the critical value Z0.05=1.645 for a 90 percent confidence interval) a. About 25 students b. About 35 students c. About 17 students d. About 188 students
The speed of light is measured 25 times by a new procedure. The 25 measurements are recorded, and show no trend or pattern. The investigators work out the average and SD of the 25 measurements; the average is 299,789.2 kilometers per second and the SD is 12 kilometers per second. (Assume the Gauss model, with no bias.) It is assumed that all units are kilometers per second. Find an approximate 95%-confidence interval for the speed of light. Enter numeric answers for the lower and upper endpoints of the interval here; be sure to show your work. (a) The 95% confidence interval for the speed of light is to . (b) Now the investigators measure the speed of light a 26th time by the same procedure, and get 299,781 kilometers per second. Is this a surprising result? Answer yes or no, and explain your reason.
otal plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that a random sample of 46 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasma per kilogram body weight). Assume that ? = 7.50 ml/kg for the distribution of blood plasma. (a)Find a 99% confidence interval for the population mean blood plasma volume in male firefighters. What is the margin of error?

CONFIDENCE INTERVAL AND THE CENTRAL LIMIT THEOREM 1. A nutritionist is interested in monitoring the calorie intake of woman. It was found that in selected a random sample of 50 female adults, the average daily intake of meat products is 2200 calories per day with the standard deviation of 300 calories. Give a 99% confidence interval for the mean intake of calories from meat products of female adults. 2.Give a 90%, 95% and 99% confidence interval of the mean weight of fresh orange if 100 randomly selected fresh orange have a mean weight of 180 grams and standard deviation f 30g (3 answers)
What price do farmers get for their watermelon crops? In the third week of July, a random sample of 44 farming regions game a sample mean of x=$6.88 per 100 pounds of watermelon. Assumed that o is known to be $1.96 per 100 pounds. find a 90% confidence interval for the population mean price (per 100 pounds) that farmers in this region get for their watermelon crop. What is the margin for error? Lower limit? Upper limit? Found two decimal places
Data on the weights (lb) of the contents of cans of diet soda versus the contents of cans of the regular version of the soda is summarized to the right. Assume that the two samples are independent simple random samples selected from normally distributed populations, and do not assume that the population standard deviations are equal. A. The test statistic, t, is (Round to two decimal places as needed.) B. The P-value iS. (Round to three decimal places as needed.) C. Construct a confidence interval appropriate for the hypothesis test lb less than mu 1 minus mu 2less than lb (Round to three decimal places as needed.)

X1=16, n1=70, x2=20, n2=30, α=0.10 Sample proportion p1=0.229 Sample proportion p2=0.667 Pooled sample proportion Pp is 0.36, I calculated the test statistic to be z=-4.18. For α=0.10, identify the critical value(s). Use the two proportions z interval procedure to find the 80% confidence interval.
Life of Smoke Detectors The average lifetime of smoke detectors that a company manufactures is 5 years, or 60 months, and the standard deviation is 8 months. Find the probability that a random sample of 30 smoke detectors will have a mean lifetime between 58 and 63 months. Assume that the sample is taken from a large population and the correction factor can be ignored. Round the final answer to at least four decimal places and intermediate z-value calculations to two decimal places. =P<58<X63
Sample observations on stabilized viscosity of asphalt specimens are 2781, 2900, 3013, 2856, and 2888. Suppose that for a particular application it is required that true average viscosity be 3000. Does this requirement appear to have been satisfied? State and test the appropriate hypothesis. (alpha = 0.05) Find the P-value. Calculate the confidence interval and use it to test the hypothesis in part a.
