Question
Test the claim about the mean of sample 1, µ1 has a lower than the mean of sample2, µz at the level of significance a. Assume the samples are random and independent,
and the population are normally distributed.
Claim: 41 = µ2;
a = 0.01
Assume the population variances are not equal
Given: sample 1: ī = 3037
s = 706.3
n = 205
sample 2: = 3272
s = 660.2
n = 195
• The hypothesis test is Ho: µ1 = µ2
H1: Pi
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
< µi - H2 <
