Question
Consider two data sets. Set A: n = 5; x=4 Set B: n = 50; x = 4 a) Suppose the number 23 is included as an additional data value in Set A. Computex for the new data set. Hint: add 23 toxof the original data set and divide by 6. (Round your answer to two decimal places.) x = nx To compute x for the new data set, (b) Suppose the number 23 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 23 to each data set change the mean for Set A more than it does for Set B O 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. O 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. O 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 larger value than for A.

Result:
a).
mean = (5*4+23)/6 = 7.17
b).
mean = (50*4+23)/51 = 4.37
c).
option 2
set B has a larger number of data values than A, so to find the mean of B we divide the sum of the values by a larger than for A.
