Question

Question: Each of five laboratory mice was released into a maze twice. The five pairs of times to escape were:

a. Compute d¯ and s_d.

b. Give a point estimate for μ₁ - μ₂ = μ_d.

c. Construct the 90% confidence interval for μ₁ - μ₂ = μ_d from these data.

d. Test, at the 10% level of significance, the hypothesis that it takes mice less time to run the maze on the second trial, on average.
