A random sample of size n₁ = 25, taken from a normal population with a standard deviation o₁ = 6, has a mean x₁ = 77. A second random sample of size n₂ = 34, taken from a different normal population with a standard deviation σ2 = 3, has a mean x2 = 37. Find a 92% confidence interval for µ – M2. Click here to view page 1 of the standard normal distribution table. Click here to view page 2 of the standard normal distribution table. The confidence interval is (Round to one decimal place as needed.)
