You are comparing two population means, say population A and population B. By doing that, you are calculating a 90% confidence interval for the difference means for sample A and sample B. This 90% confidence interval yields μA - μB = (-2.876, 5.398)
Based on this 90% confidence interval, a student concluded that the mean of population A is more than the mean of population B.
True
False
From the given information,
Null and Alternative hypothesis is,
H0:mean of population A same as the mean of population B.
Ha:mean of population A is more than the mean of population B.
This 90% confidence interval yields μA - μB = (-2.876, 5.398)
The given confidence interval include 0.
Hence, we fail to reject null hypothesis (H0)
Based on this 90% confidence interval, a student concluded that the mean of population A is more than the mean of population B.
False
