Consider two data sets.

Set A:n= 5;x=7Set B:n= 50;x=7

(a) Suppose the number11is included as an additional data value in Set A. Computex

for the new data set. Hint:x=nx.

To computex

for the new data set, add11tox

of the original data set and divide by 6. (Round your answer to two decimal places.)

(b) Suppose the number11is included as an additional data value in Set B. Computex

for the new data set. (Round your answer to two decimal places.)

(c) Why does the addition of the number11to each data set change the mean for Set A more than it does for Set B?

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 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.

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 smaller value than for A.
