A large explosion causes wood and metal debris to rise vertically into the air with an initial velocity of 96 feet per second. The function h(t) = 96 t − 16 t 2 gives the height of the falling debris above the ground, in feet, t seconds after the explosion. A) Use the given function to find the height of the debris 2 second(s) after the explosion: Answer: After 2 second(s), the height is 112 Incorrect feet.

Test the claim that the two samples described below come from populations with the same mean. Assume that the samples are independent simple random samples.Sample 1: n1=24, x?? 1=14, s1=4.Sample 2: n2=28, x?? 2=9, s2=4.(a) The test statistic is ___.(b) Find the t critical value for a significance level of 0.02 for an alternative hypothesis that the first population has a larger mean (one-sided test): t?= ___.(c) The conclusion is-There is not sufficient evidence to warrant rejection of the claim that the two populations have the same mean.-There is sufficient evidence to warrant rejection of the claim that the two populations have the same mean and accept that the first population has a larger mean.
