There are 24 students enrolled in an introductory statistics class at a small university. As an in-class exercise the students were askedhow many hours of television they watch each week. The nm = 13 male students watched an average of 6 hours of television per weekwith standard deviation 4.24 hours. The ng = 11 female students watched an average of 3.91 hours of television per week with astandard deviation of 3.48 hours. Assume that the students enrolled in the statistics class are representative of all students at theuniversity.The standard error of the differences , and x, is about SE = 1.667. Use the normal distribution to test, at the 5% level, if malestudents at this university watch, on average, more television than female students. Include all details of the test.z =ip-value =iThere isevidence that males at this university watch significantly more television, on average, than female students.

The pie chart shows the distribution of the opinions of parents on whether a college education is worth the expense. An economist claims that the distribution of the opinions of teenagers is different from the distribution for parents. To test this claim, you randomly select 197 teenagers and ask each whether a college education is worth the expense. Strongly agree The table to the right shows the results. At a = 0.05, test the economist's claim. Click the icon for the pie chart of the distribution. Response Somewhat agree Neither agree nor disagree Somewhat disagree Strongly disagree Survey results State Ho and H₂ and identify the claim. Ho: The distribution of the opinions of whether a college education is worth the expense is the same for teenagers and parents.

The pathogen Phytophthora capsici causes bell peppers to wilt and die. Because belI peppers are an important commercial crop, this disease has undergone a great deal of agricultural research. It is thought that too much water aids the spread of the pathogen. Two fields are under study. The first step in the research project is to compare the mean soil water content for the two fields. Units are percentage of water by volume of soil.
