A magazine reported that at the top 50 business schools in a region, students studied an average of 18.1 hours. Set up a hypothesis test to try to prove that the mean number of hours studied at your school is different from the reported 18.1 hour benchmark. State the null and alternative hypotheses.
A food company claims a population mean of 625 calories in their frozen lasagna entrées. A sample of 50 of these entrees were collected for a hypothesis test. The null hypothesis is that the population mean calories is 625. The alternative hypothesis is that the population mean calories is higher than 625. Below are the test results. At the 5% significance level, what is the conclusion of the test? There is not enough evidence to conclude the population mean number of calories in the entrees is more than 625. There is enough evidence to conclude the population mean number of calories in the entrees is more than 625. The mean is 630. The mean is 625.
A manager states that in his warehouse, the average number of days per year missed by the employees due to illness is less than the national average of twelve. The manager took a sample of 60 employees and found that the mean number of days missed due to illness was 10.1 days. If 0 = 4. 28 and a = 0. 01, determine if there is sufficient evidence to believe the manager's statement Please show all work in performing your hypothesis test below. Be sure to include null and alternative hypotheses, critical value, tes value and your conclusion.
A sample of 45 households reveals that 23% have traveled overseas. Is this significantly different from a hypothesized value of 30%, which characterizes the entire country?

The city manager measures response times by looking at the proportion of calls for which paramedics arrived within 8 minutes. Last year, paramedics arrived on scene 75% of the time within 8 minutes. The city manager wants to determine whether they have done significantly better this year. State appropriate null and alternative hypotheses for the city manager to test. Describe a Type I and Type II error in this setting. Explain the consequences of each type of error. Which is more serious: a Type I error or a Type II error? Justify your answer
