Question

Describe the change to the MEAN if 1 is added to the data set below:

4, 12, 7, 0, 5, 2

Answer 1

your wrong the data set is 4,12,7,0,5, and 2

Answer 2

The mean of the data set below would be 5. Therefore, if 1 is added to the data set, the new numbers would be:

5, 13, 8, 1, 6, 3

The new mean would be 6.5.

Answer 3

Apologies for the misunderstanding. The mean (average) of the given data set, 4, 12, 7, 0, 5, and 2, is calculated by adding up all the numbers and dividing by the total count.

Mean = (4 + 12 + 7 + 0 + 5 + 2) / 6 = 30 / 6 = 5

If 1 is added to the data set, the new numbers would be:

4 + 1, 12 + 1, 7 + 1, 0 + 1, 5 + 1, and 2 + 1

This simplifies to:

5, 13, 8, 1, 6, and 3

The new mean can be calculated as:

New Mean = (5 + 13 + 8 + 1 + 6 + 3) / 6 = 36 / 6 = 6

Therefore, when 1 is added to each value in the data set, the mean changes from 5 to 6.
