Answer:

B) 19, 25, 31

Step-by-step explanation:

Given:- The given five values are 15, 24, 18, 33, 42.

To Find:- The three years moving averages.

Solution:-

The given five values are 15, 24, 18, 33, 42.

We calculate three years moving averages by following steps:-

1. Add up the 1st 3 numbers in the list and divide it by 3. This will be 1st 3 years moving average.

2. Add up the next 3 numbers in the list and divide the sum by 3. This will be second 3 years moving average.

3. Keep repeating step 2 until reached the last 3 numbers.

Average of 1st 3 values = (15 + 24 + 18) ÷ 3

                                       = 57 ÷ 3  = 19

Average of next 3 values = (24 + 18 + 33) ÷ 3

                                          = 75 ÷ 3  = 25

Average of last 3 values = (18 + 33 + 42) ÷ 3

                                         = 93 ÷ 3  = 31

Therefore, the 3 years moving averages are 19, 25, 31.

The correct option is B) 19, 25, 31
