Step 1: Compute the mean and the standard deviation of the resting metabolic rates ( y variable, measured in calories burned per day) and lean body masses ( x variable, measured in kilograms) of the following 19 subjects participating in a study of dieting, and the correlation between these two variables: Subject Sex Mass Rate Subject Sex Mass Rate M 62.0 1792 11 F 40.3 1189 N M 62.9 1666 12 F 33.1 913 + w 36.1 995 13 M 51.9 1460 F 54.6 1425 14 F 42.4 1124 F 48.5 1396 15 34.5 1052 42.0 1418 16 F 51.1 1347 M 47.4 1362 17 F 41.2 1204 F 50.6 1502 18 M 51.9 1867 F 42.0 1256 19 M 46.9 1439 10 M 48.7 1614 Data Set Use these values to find the slope of the regression line of metabolic rate on lean body mass. Fill in the blank (give your answers to the required decimal places, however always remember to keep a few more figures in your interim calculations) : 1) The mean of the mass variable is (give your answer in units of kg to 2 decimal places): kg. 2) The mean of the rate variable is (give your answer in units of cal/day to 1 decimal place): cal/day. 3) The standard deviation of the mass variable is (give your answer in units of kg to 3 decimal places): kg. 4) The standard deviation of the rate variable is (give your answer to in units of cal/day 1 decimal place): cal/day.Answer 1 46.74 Answer 2 1369.5 Answer 3 8.0611 Answer 4 250.5 U Step 2: The correlation r is (answer given to 4 decimal places): 0 0.9215 0 0.864? 0 0.5741 0 0.9958 Step 3: The slope of the regression line of metabolic rate on lean body mass is (answer given to 1 decimal place, units discussed in the last section of the problem): 0 26.9 0 72.3 m 1.0 \\_z m 86.5 Step 4: The slope of the regression line of lean body mass on metabolic rate is (answer given to 4 decimal places, units discussed in the last section of the problem): O 0.0154 O 0.0986 O 0.0278 O 0.0587Step 5: What units does the slope of each of the regression lines have? For each regression line, match the correct answer: cal day he .2. [] do}; 3. kg cal 4. day he 1. Enter the number of the term that corresponds to each choice: 1. Units of the slope of the regression line for predicting metabolic rate from lean bod'glr mass 2. Units of the slope of the regression line for predicting lean body:r mass from metabolic rate
