The following information is obtained from two independent samples selected from two
populations.
Description
The following information is obtained from two independent samples selected from two
populations.
a. What is the point estimate of μ1 - μ2?
b. Construct a 95% confidence interval for μ1 - μ2. Find the margin of error for this estimate.
Ans:
Data
a). What is the point estimate of μ1 - μ2?
Point estimate is the difference between the two sample means.
Point estimate = (µ1 – µ2) = 1.05 – 1.54 = (0.49)
Point Estimate = 0.49
b). Construct a 95% confidence interval for μ1 - μ2.
Find the margin of error for this estimate.
