In a recent study of the carbohydrate contents of grilled chicken sandwiches served at fast food restaurants, a nutritionist found that random samples of sandwiches from Restaurant A and from Restaurant B had the sample statistics shown in the table. Construct a 95% confidence interval for σ₁²/σ₂², where σ₁² and σ₂² are the variances of the carbohydrate contents of grilled chicken sandwiches from Restaurant A and Restaurant B, respectively.

Construct the confidence interval for σ₁²/σ₂². Assume the samples are random and independent, and the populations are normally distributed.
