Question

Consider the following results for independent random samples taken from two populations.

Sample 1	Sample 2
n ₁ = 10	n ₂= 30
x ₁ = 22.5	x ₂ = 20.3
s ₁ = 2.1	s ₂ = 4.9

What is the point estimate of the difference between the two population means (to 1 decimal)?
What is the degrees of freedom for the t distribution (round down your answer to nearest whole number)?
At 95% confidence, what is the margin of error (to 1 decimal)?
What is the 95% confidence interval for the difference between the two population means (to 1 decimal)?
