1) Calculate the sample standard deviation of the variable waiting time.The value of the sample standard deviation:2) Calculate the range of the variable waiting time.The value of the range:3) Calculate the interquartile range4) Any value of the variable with Z score less than -3.0, or greater than +3.0 isclassified as outliers. Check whether the minimum and maximum are outliers.The formula for calculation of z score is as following:Z = (x-u)/0 = (x - x)/su: population meano: population standard deviationx : the sample means: the sample standard deviationWhen you calculate the z value, use the sample mean to replace the populationmean, and sample standard deviation to replace population standard deviation-The value of the z score of the minimum:-The value of the z score of the maximum:-Any outliers and explanation:

Question B2 The waiting time (in days) for a service were collected. The summary statis given in the following table. Summary statistics of waiting time Mean 14.00 Standard Error 0.40 Median 14.00 Mode 17.00 Standard Deviation Sample Variance 25.00 Kurtosis -0.54 Skewness 0.05 Range Minimum 2.00 Maximum 30.00 Sum 3082.00 Page BUGEN1502 2021 SEM 2 Exam Paper Count 220.00 first quartile 10.00 second quartile 14.00 third quartile 18.00 interquartile range
