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
mean	98.033	98.633	97.633
standard deviation	0.48	0.484	0.339

The variance between samples is $ns_{\overline{x}}^2 =$ The variance within samples is $s_p^2 =$ The test statistic is $F =$ The critical value is $F =$ 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
