Answer 1

To calculate mean and standard deviation mean of sample = {xi X= 71, 102, 132, 127, 60,64 - 21+ 102+132 +12 7 +60+64 M 556 = 92.66667 standard deviation of sample : {(x-x) ² n- = [469.44444,87111111, 1547.1111), 1178.77778, 1067.11111, 821.77777 E(x-7)= 5171.33333 5171.3333 sa V1034.26667 5371.3333 = V1034.26667 6-) s 32:16001658
