Metabolic Rates: a persons metabolic rate is the rate at which the body consumes

Question

Metabolic Rates: a persons metabolic rate is the rate at which the body consumes energy. Metabolic rate is important in studies of weight gain, dieting, and excercise. Here are the metabolic rates of 7 men who took part in a study of dieting. The units are per calories per 24 hours
1792 1666 1362 1614 1460 1867 1439
A) find the mean of the data B) find the deviations for each data point and their squares C) calculate the variance as an average of the squared deviations then obtain s as the square root of the variance Metabolic Rates: a persons metabolic rate is the rate at which the body consumes energy.

Explanation / Answer

a)

Mean of 7 observations = 1600

b)

c)

Sum of squared deviation = 214870

Average of sum of squared deviation = 214870/7 = 30685.71

s = sqrt(30685.71) = 175.2

Observation Deviation Square of devaition 1792 192 36864 1666 66 4356 1362 -238 56644 1614 14 196 1460 -140 19600 1867 267 71289 1439 -161 25921
