When we compute the sample mean and sample standard deviation for the transaction times, we find that x = 36.56 and s = 4.475. Compute each of the intervals [x ± s], [x ± 2s], and [x ± 3s]. Then count the number of transaction times that actually fall into each interval and find the percentage of transaction times that actually fall into each interval. (Round your answers to 3 decimal places. Omit the "%" sign in your response.)
