Distribution is skewed right (b)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 [xt 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.) [x±s] [x ±2s] [x ± 3s] []: % 95.23% 96.83 %
