According to the South Dakota Department of Health, the mean number of hours of TV viewing per week is higher among adult women than men. A recent study showed women spent an average of 33 hours per week watching TV and men 28 hours per week. Assume that the distribution of hours watched follows the normal distribution for both groups, and that the standard deviation among the women is 4.2 hours and is 4.9 hours for the men. (a) What percent of the women watch TV less than 38 hours per week? (Round z-score computation to 2 decimal places and your final answer to 4 decimal places.) Probability (b) What percent of the men watch TV more than 25 hours per week? (Round z-score computation to 2 decimal places and your final answer to 4 decimal places.) Probability (c) How many hours of TV do the three percent of women who watch the most TV per week watch? Find the comparable value for the men. (Round your answers to 3 decimal places.) Number of hours Women Men,Hi Natalia, In the answer for a) = P(Z< 1.19) = .883 How do you get to .883 from P(Z
