10)The U.S. Bureau of Labor and Statistics reported that a person between the agesof 18 and 34 has had an average of 9.3 jobs. To see if this average is correct, aresearcher selected a random sample of 8 workers between the ages of 18 and 34and asked how many different places they had worked. The results were asfollows:11482814136At α= 0.05, can it be concluded that the mean is 9.2? Use the P-value method.10)11)The mean annual tuition and fees for a sample of 15 private colleges was $36,700with a standard deviation of $6,500. A dotplot shows that it is reasonable toassume that the population is approximately normal. You wish to test whether themean tuition and fees for private colleges is different from $33,300.Compute the value of the test statistic and state the number of degrees offreedom.11)MULTIPLECHOICE.Choosetheonealternativethatbestcompletesthestatementoranswersthequestion.12)Determine whether the outcome is a Type I error, a Type II error, or a correct decision.A test is made of H0: μ= 28 versus H1: μ≠28.

14)The null hypothesis states that there is no difference between a parameter and a specificvalue, or that there is no difference between two parameters.
