A recent study showed women spent an average of 34 hours per week watching TV and men 29 hours per week (www.state.sd.us/DOH/Nutrition/TVpdf) Assume that the distribution of hours watched follows the normal distribution for both groups, and that the standard deviation among the women is 4.5 hours and is 5.1 hours for the men. . What is the 2 score for a woman who watches 30 hours of TV per week? b. What is the z score for a man who watches 30 hours of TV per week? c. Who, with regard to their own distribution, actually watches the least TV?Explanation / Answer
