The table below lists the body temperatures of six randomly selected subjects from each of three different age groups. Use the $\alpha = 0.05$ significance level to test the claim that the three age-group populations have different mean body temperatures.

	16-20	21-29	30 and older
subject 1	97.4	98.6	97.2
subject 2	98.5	99.4	97.8
subject 3	97.5	98.9	97.6
subject 4	98.2	98.3	98.1
subject 5	98.5	98.6	97.3
subject 6	98.1	98	97.8

Note: $T_1 =$ 588.2, $T_2 =$ 591.8 , $T_3 =$ 585.8 and $\Sigma x^2 =$ 173230.92

The test statistic is $F =$

The critical value is $F_\alpha =$

Is there sufficient evidence to warrant the rejection of the claim that the three age-group populations have the same mean body temperature?
A. Yes
B. No
