Question

FOR THIS AND THE NEXT QUESTION. According to The Boston Globe (August 16, 2010), Asian residents in Boston have the highest average life expectancy of any racial or ethnic group. The report shows, in particular, that Asians live a decade longer than black residents. Suppose the sample results below are indicative of the overall results. Calculate the F statistic.

	Asian	Black	Latino	White
Sample mean	83.70	73.50	80.60	79.00
Sample variance	26.30	27.50	28.20	24.80
Sample size	20	20	20	20

		79.20
		13.67
		2.72
		26.70
		None of the above

Suppose the p-value for the above study = 0.00. Which of the following conclusions with respect to the study is correct?

		At the 5% level, do not reject the null hypothesis. Average life expectancy differs across the four racial groups
		At the 1% level, reject the null hypothesis. Average life expectancy is the same across the four racial groups
		At the 1% level, reject the null hypothesis. Average life expectancy differs across the four racial groups
		None of the above
