A paper reported that in a representative sample of 291 American teens age 16 to 17, there were 79 who indicated that they had sent a text message while driving. For purposes of this exercise, assume that this sample is a random sample of 16- to 17-year-old Americans. Do these data provide convincing evidence that more than a quarter of Americans age 16 to 17 have sent a text message while driving? Test the appropriate hypotheses using a significance level of 0.01.

In a representative sample of 50 American households, 32 households had a pet. Use this sample data to answer the following questions. A. Use Minitab Express to construct a 95% confidence interval to estimate the proportion of all American households with a pet. Show how you checked assumptions. If assumptions were met, use the normal approximation method. Remember to include all relevant Minitab Express output and to clearly identify your answer. Other than checking assumptions, do not do any hand...
