The technical operations department wants to ensure that the mean target upload speed for all Internet service subscribers is at least 0.97 on a standard scale in which the target value is 2.0. Each day, upload speed was measured 50 times, with the following results: 0.854+x 1.023+x 1.005+x 1.030+x 1.219+x 0.977+x 1.044+x 0.778+x 1.122+x 1.114+x 1.091+x 1.086+x 1.141+x 0.931+x 0.723+x 0.934+x 1.060+x 1.047+x 0.800+x 0.889+x 1.012+y 0.695+y 0.869+y 0.734+y 1.131+y 0.993+y 0.762+y 0.814+y 1.108+y 0.805+y 1.223-Z 1.024-z 0.884-z 0.799-Z 0.870-z 0.898-Z 0.621-Z 0.818-z 1.113-z 1.286-Z 1.052-z 0.678-z 1.162-Z 0.808-Z 1.012-Z 0.859-z 0.951-z 1.112-z 1.003-z 0.92-z In the above table, Becareful that x and y are supposed to be added and z is to be subtracted. x = 0.15 and z = 45 y = 0.2 Accomplish the following tasks: 1- Find mean, standard deviation, and five number summary for this dataset. Specify if there is any outlier. 2- Plot histogram and boxplot. 3- Compute the sample statistic and determine whether there is evidence that, the population mean upload speed is less than 0.97.
