Problem
A person recorded the number of minutes they watched TV each weekday of last week. Find the standard deviation of this population data set. If the answer is a decimal, round it to the nearest tenth.
Answer
\(6.3\)
Step-by-step solution
Calculate the mean, then the variance, and finally the standard deviation of the given data set (55, 60, 70, 65, 60). The mean is 62. The variance is approximately 12.8. The standard deviation is the square root of the variance.
