he local bakery bakes more than a thousand 1-pound loaves of bread daily, and the weights of these loaves varies. The mean weight is 0.9 lb. and 1 oz., or 437 grams. Assume he standard deviation of the weights is 21 grams and a sample of 45 loaves is to be randomly selected. (a) This sample of 45 has a mean value of x, which belongs to a sampling distribution.

Recent studies have shown that about 16% of American adults fit the medical definition of being obese. A large medical clinic would like to estimate what percentage of their patients are obese, so they take a random sample of 400 patients and find that 52 are obese. Suppose that in truth, the same percentage holds for the patients of the medical clinic as for the general population, 16%. Find the mean of the sampling distribution of p̂.
Between 2000 and 2010, Major League Baseball teams have an average of 1.07 home runs per game. Some statisticians have suggested that there is a different average number of home runs per game hit today than in year's past. To test this claim, we collected a random sample of 91 baseball games in 2017 and found that 142 home runs were hit with a sample standard deviation of 1.89. (a) Perform a six-step hypothesis test to see if the average number of home runs in 2017 differs from 1.07. Use a = 0.05. (b) Use the same Ho and H₂ that you use in part (a). Does the conclusion change when you shift the level of confidence to a = = 0.01?
The annual salary for one particular occupation is normally distributed, with a mean of about $132,000 and a standard deviation of about $16,000. Random samples of 26 are drawn from this population, and the mean of each sample is determined. Find the mean and standard deviation of the sampling distribution of these sample means. Then, sketch a graph of the sampling distribution.
