Question

A persons metabolic rate is the rate at which the body consumes energy. Metabolic rate is important in studies of weight gain, dieting, and exercise. Here are the metabolic rates of 7 men who took part in a study of dieting. (The units are calories per 24 hours. These are the same calories used to describe the energy content of foods.) 1752 1635 1318 1614 1460 1867 1414 Calculate the mean and standard deviation of the metabolic rates, showing each step in detail. First find the mean by summing the 7 observations and dividing by 7. Then find each of the deviations 지-_ and their squares, what is the sum of the deviations? Calculate the variance as an average of the squared deviations (remember to divide by n -1). Finally, obtain s as the square root of the variance. (Round your answer to two decimal places.)
