Question
Consider two data sets. Set A: n = 5; x = 4 Set B: n = 50; x = 4 (a) Suppose the number 14 is included as an additional data value in Set A. Computex for the new data set. Hint: …x. To compute x for the new data set, add 14 to x of the original data set and divide by 6. (Round your answer to two decimal places.) (b) Suppose the number 14 is included as an additional data value in Set B. Compute x for the new data set. (Round your answer to two decimal places.) (c) Why does the addition of the number 14 to each data set change the mean for Set A more than it does for Set B? Set B has a smaller number of data values than set A, so to find the mean of B we divide the sum of the values by a larger value than for A. Set B has a larger number of data values than set A, so to find the mean of B we divide the sum of the values by a larger value than for A. Set B has a larger number of data values than set A, so to find the mean of B we divide the sum of the values by a smaller value than for A. Set B has a smaller number of data values than set A, so to find the mean of B we divide the sum of the values by a smaller value than for A Need Help? Master It Talk to a TutorExplanation / Answer
a)new data set total =5*4+14 =34
hence Xbar =34/6=5.67
b) as from above average xbar =(50*4+14)/51 =4.20
c)
2nd option is corrrect : set B has larger number of data//////.........../// larger value then that of A.
