The height of women ages 20-29 is normally distributed, with a mean of 642 inches. Assume o = 27 inches. Are you more likely to randomly select 1 woman with a height less than 65.4 inches or are you more likely to select a sample of 15 women with a mean height less than 65.4 inches? Explain.

A survey found that women's heights are normally distributed with mean 63.6 in and standard deviation 2.5 in. A branch of the military requires women's heights to be between 58 in and 80 in. a. Find the percentage of women meeting the height requirement. Are many women being denied the opportunity to join this branch of the military because they are too short or too tall? b. If this branch of the military changes the height requirements so that all...

A standardized exam's scores are normally distributed In a recent year, the mean test score was 1495 and the standard deviation was 315. The test scores of four students selected at random are 1900, 1240, 2230, and 1400 Find the z-scores that correspond to each value and determine whether any of the values are unusual The z-score for 1900 is (Round to two decimal places as needed) The Z-score for 1240 is (Round to two decimal places as needed.)

In a test of the effectiveness of garlic for lowering cholesterol, 49 subjects were treated with garlic in a processed tablet form. Cholesterol levels were measured before and after the treatment. The changes (beforeminus−after) in their levels of LDL cholesterol (in mg/dL) have a mean of 5.2 and a standard deviation of 16.5 Construct a 90% confidence interval estimate of the mean net change in LDL cholesterol after the garlic treatment. What does the confidence interval suggest about the effectiveness...
In a test of the effectiveness of garlic for lowering cholesterol, 49 subjects were treated with garlic in a processed tablet form. Cholesterol levels were measured before and after the treatment. The changes in their levels of LDL cholesterol (in mg/dL) have a mean of 5.7 and a standard deviation of 17.3. Complete parts (a) and (b) below. a. What is the best point estimate of the population mean net change in LDL cholesterol after the garlic treatment?b. Construct a...
