A manufacturer of detergent claims that the contents of boxes sold weigh on average at least 20 ounces. The distribution of weight is known to be normal, with a standard deviation of 0.5 ounces. A random sample of 16 boxes yielded a sample mean weight of 19.71 ounces.

We are interested in seeing if there is a difference between how long women and men spend shopping at Costko-K. Men spend an average of 48 minutes in our store with a standard deviation of 22 minutes. Women spend an an average of 39 minutes in our store with a standard deviation of 9 minutes. The sample size for men is 250 and the sample size for women is 300. Test the hypothesis at a 95% confidence level. Show your calculations and explain your findings.
A random sample of 49 cans of soda is obtained and the contents are measured. The sample mean is 12.01 oz and the standard deviation is 0.13 oz.

Suppose a pitcher claims that his pitch speed is more than 55 miles per hour, on average. Several of his teammates do not believe him, so the pitcher decides to do a hypothesis test, at a 5% significance level, to persuade them. He throws 81 pitches. The mean speed of the sample pitches is 63 miles per hour. The pitcher knows from experience that the standard deviation for his pitch speed is 9 miles per hour.

A report states that the mean yearly salary offer for students graduating with a degree in accounting is $48,722. Suppose that a random sample of 50 accounting graduates at a large university who received job offers resulted in a mean offer of $49,870 and a standard deviation of $3900. Do the sample data provide strong support for the claim that the mean salary offer for accounting graduates of this university is higher than the national average of $48,722?

A 0.01 significance level is used for a hypothesis test of the claim that when parents use a particular method of gender selection, the proportion of baby girls is different from 0.5. Assume that sample data consists of 55 girls in 100 births, so the sample statistic of 1120 results in a z score that is 1 standard deviation above 0.

Choose the appropriate statistical test. When computing, be sure to round each answer as indicated. A dentist wonders if depression affects ratings of tooth pain. In the general population, using a scale of 1-10 with higher values indicating more pain, the average pain rating for patients with toothaches is 6.8. A sample of 30 patients that show high levels of depression have an average pain rating of 7.1 (variance 0.8). What should the dentist determine? 1. Calculate the estimated standard error.
