Transcribed Image Text:Test the claim about the mean of sample 1, µ1 has a lower than the mean of sample2, µ2 at the
level of significance a. Assume the samples are random and independent, and the population are
normally distributed.
Claim: H1
= µ2;
a = 0.01
Assume the population variances are not equal
Given: sample 1: = 3037
S = 706.3
n = 205
%3D
sample 2: = 3272
S = 660.2
n = 195
The hypothesis test is Ho: µ1 = µ2
H1: H1
Answer choose one of these: Type A for =; Type B for < ; Type C for > and Type D for =
Test statistic: t =
(Two decimal places.)
P- value is
(four decimal places. )
Construct confidence interval at a = 0.10
