two potential vendor's MUML i8 investigating their deliveries. on the timeliness of a of size 8 from the random Sample first an average delay vendor produced time of 3.5 days with a standard deviation of 2 days. A random Samples of Size 10 from the second vendor yield an average deby time of 3 days with a standard deviation of 4.5 days. a) Finch a 90% confidence interval for the ratio of the variances of the delay times for two vendors. b) can we calculate that the first vendor has a Smaller variability regarding delay times than the Second ? use a significance level of 0105
