The burning rates of two different solid-fuel propellants used in aircrew escape systems are being studied is known that both propellants have approximately the same standard deviation of burning rate; that is 3 centimeters per second. Two random samples of n1 = 20 and n2 = 20 specimens are tested; the sample mean burning rates are X-bar 1 = 18 centimeters and x-bar 2 - 24 centimeters per second.
a) Construct a 95% confidence interval on the difference in means. [1] Lower [2] Upper [3] Tabular value (3 decimal places)
b) Construct a 90% Upper confidence interval bound of the difference in means [4] Upper [5] Tabular value (3 decimal places)
