An article in Fire Technology (LR DİMaio, PJ Chiesa, MS Ott - Fire technology, 1975 - Springer, p. 164-174) investigated two different foam expanding agents that can be used in the nozzles of fire-fighting spray equipment. A random sample of five observations with an aqueous film-forming foam (AFFF) had a sample mean of 4.5 and a standard deviation of 0.59. A random sample of five observations with alcohol-type concentrates (ATC) had a sample mean of 6.7 and a standard deviation 0.85. Construct the following: (a) A 90% two-sided confidence interval on. Round your answer to three decimal places (e.g. 98.765). (b) A 95% two-sided confidence interval on o /o.Comment on the comparison of the width of this interval with the width of the interval in part (a). Round your answer to three decimal places (e.g. 98.765). The 95% confidence interval is than the 90% confidence interval. (c) A 90% lower-confidence bound on of lo;.
