Question
Construct the 90% interval estimate for the ratio of the population variances using the following results from two independently
drawn samples from normally distributed populations. (Round "F"' value and final answers to 2 decimal places. You may find it
useful to reference the appropriate table: chi-square table or Ftable)
Sample 1:1= 152, s² = 20.4, and m₁ = 6
Sample 2: 2 = 147.6, s² = 17.7, and n₂ = 5
X Answer is complete but not entirely correct.
Confidence interval
7.41 X to
290.94 X
