The average age of pet dogs is 4.3 years. Two random samples of pet owners who own dogs are selected. Sample 1 of 13 dog owners was selected from owners who live in Miami. The standard deviation of the ages of the dogs in this sample is 1.3 years. Sample 2 of 8 dog owners was selected from dog owners who live in Boston. The standard deviation of these dogs was 0.7 year. At α = 0.05, can it be concluded that there is a difference in the variances?
