MODULE 11 1. A population has a mean of ED and standard of 5. A random sample of 15 measurements is drawn from this population. Decsribe the sampling distribution of the sample means by computing its mean and standard deviation. l 5 points :I 2. The heights of male college students are normally distributed with mean of 63 Inches and standard deviation of 3 inches. if 30 samples consisting of 25 students each are draWn from the population, what would be the expected mean and standard deviation of the resulting sampling dismhut'ron of the means? i 5 points ] Module 12 3. Consider a population consisting of 1r 2. 3, ii. and 5. Suppose samples of size 3 are drawn from this population. Describe the sampling distribution of the sample means. llWhat is the mean, varianoe and standard deviation of the sampling distribution of the sample means? [ 10 points} Module 15 4. Manufacturer of ball bearings claims that this product has a mean weight of 5.02 g and standard deviation of {3.30 g. What is the probability that a random sample of 100 ball hearings will have combined weight: a. more than 5.10 g? [5 points] In. Between 4.96 g and 5.00 g? { 11'.) points l
