An article in Fire Technology describes the investigation of two different foam expanding agents that can be used in the nozzles of firefighting spray equipment. A random sample of five observations with an aqueous film-forming foam (AFFF) had a sample mean of 4.340 and a standard deviation of 0.508. A random sample of five observations with alcohol-type concentrates (ATC) had a sample mean of 7.091 and a standard deviation of 0.430. Assume that both populations are well represented by normal distributions with the same standard deviations. Construct the following: (A) A 90% two-sided CI on 𝜎𝜎1/𝜎𝜎2. (B) A 95% two-sided CI on 𝜎𝜎1/𝜎𝜎2. Comment on the comparison of the width of this interval with the width of the interval in part (A). (C) A 90% lower-confidence bound on 𝜎𝜎1/𝜎𝜎2.
