1. Calculate the following values: 18, 20, 25, 28, 30, 32, 33

a. Calculate the mean, the median, and the mode

b. Add 10 to each value and recalculate the mean. Compare the result with the value obtained in (a).

c. Subtract 10 to each value and recalculate the mean. Compare the result with the mean in (a).

d. Multiply each value by 2 and recalculate the mean. How does the result compare with the mean in (a).

e. Make a generalization based on your computation.

f. Can you make a similar generalization if the values are each divided by a constant?
