Consider a model for how frequently yarn breaks during weaving. Wool has two levels, A and B, and tension of the yarn has three levels, L = Low, M = Medium, and H = High. The coefficient of WoolB is -0.20599, with a standard error of 0.05157. Calculate the upper end of a 95% confidence interval for the ratio of mean number of breaks wool B to A [that is (mean count B)/(mean count A)]Give your answer to two decimal places.
