A person's 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 rate 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. Calculate the mean, and standard deviation of metabolic rate showing each step in the detail.

1772 1655 1369 1614 1460 1867 1435

Find the mean by summing the 7 observations and diving by 7-

then find each of the deviations-

Calculate the variance as an average of the squared deviation-

finally obtain as the square root of the variance-
