Assume that both populations are normally distributed. (a) Test whether mu 1 not equals mu 2μ1≠μ2 at the alpha equals 0.01α=0.01 level of significance for the given sample data.		Population 1	Population 2
	n	17	17
	x bar	14.614.6	19.819.8
	s	4.24.2	3.73.7

Determine the P-value for this hypothesis test.

P=?(Round to three decimal places as needed.)
