Question

7 In a study on survival time for ten patients following a new treatment for AIDS. The time in months were given thus: 24, 12, 8, 20, 3, 18, 24, 25, and 27. Determine the mean for the given data.

20

17.9

24

6.8

Solution

The mean of several numbers equals the sum of those numbers divided by the quantity of numbers.

Thus, the mean for 24, 12, 8, 20, 3, 18, 24, 25, and 27 will be

$$(24 + 12 + 8 + 20 + 3 + 18 + 24 + 25 + 27) / 9 = 161 / 9 \approx 17.9.$$

Answer: 17.9.
