Refer to the data in images. Test for a significant difference in the variances of theinitial white blood cell count between patients who did andpatients who did not receive a bacterial culture.
Effectiveness of Hypnotism in Reducing Pain. A study was conducted to measure the effectiveness of hypnotism in reducing pain. The measurements are in centimeters on a pain scale before and after hypnosis. Assume normality assumption is satisfied for this case. Use a 0.025significance level to test the the effectiveness of hypnotism in reducing pain. The two samples are dependent/matched. So you need to find the differences first, the calculated the mean and the standard deviation of the differences D = 2.05, sD = 1.524.

A researcher wants to measure average cardiovascular health of university students and compare those scores to the average scores in the general population. Assuming that population variance is known, what statistical test(s) seem most appropriate for the study? (Cardiovascular health is represented by how many seconds it takes for the heart rate to return to baseline after a stress test). Paired samples t-test Independent samples t-test z-test for the sample mean ANOVA
Scores on a certain test are normally distributed with a variance of 15. A researcher wishes to estimate the mean score by all adults on the test. Find the sample size needed to assure with 98% confidence that the sample mean will not differ from the population mean by more than 4 units.
On a television show, eight contestants try to lose the highest percentage of weight in order to win a cash prize. As part of the show, the contestants are timed as they run an obstacle course. The table shows the times (in seconds) of the contestants at the beginning of the season and at the end of the season. At a=0.10, is there enough evidence to support the claim that the contestants' times have changed? Assume the samples are random and dependent, and the population is normally distributed. Complete parts (a) through (e) below. Contestant 1 2 3 4 5 6 7 8 Time (beginning) 130.8 132.1 131.7 141.3 126.8 153.5 120.7 Time (end) 154.8 124.7 127.6 127.9 138.8 112.6 150.7 109.4 140.0 (a) Identify the claim and state Ho and Ha What is the claim? OA. The contestants' times have changed. B. The contestants' times have decreased. OC. The contest have increased. OD. The contestants' times have not changed.
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? (Round your answers to two decimal places.) lower limit ___ upper limit ___ margin of error ___ (b)What conditions are necessary for your calculations? (Select all that apply.) A-the distribution of volumes is uniform B-? is known C-the distribution of volumes is normal D-? is unknown E-n is large d)Find the sample size necessary for a 99% confidence level with maximal margin of error E =…

Total 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 50 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 ? = 7.20 ml/kg for the distribution of blood plasma. (d) Find the sample size necessary for a 99% confidence level with maximal margin of error E = 2.50 for the mean plasma volume in male firefighters. (Round up to the nearest whole number.) ______ male firefighters
