Use the given statistics to complete parts (a) and (b). Assume that the populations are normally distributed. (a) Test whether mu 1μ1greater than>mu 2μ2 at the alphaαequals=0.10 level of significance for the given sample data.(b) Construct a 99% confidence interval about mu 1μ1minus−mu 2μ2.		Population 1	Population 2
	n	28	20
	x overbarx	46.6	42.4
	s	4.7	10.2

Find the test statistic for this hypothesis test.

1.72

Answer 1

Answer #1

SE = sqrt(4.7^2/28 + 10.2^2/20) = 2.4476

Test statistic,
t = (46.6 - 42.4)/2.4476
t = 1.72

df = 20 - 1 = 19
p-value = 0.051
