Question

A new type flare accelerant is tested. A control of flares(x) that are currently used and a

Group of flares(y) with the new accelerant and tested for theirburning times(in minutes) and sample results are given below.

Flare x   flare y

n=35      n=40

x=19.4   x=15.1

s=1.4     s=0.8

Refer to the sample data to test the claim that the twopopulations have equal means.Use a 0.05 significance level.

Ho:=mx=my   H1: mx not equal to my

Test statistic t= 16.025 p-value=0

Would the answer be

Since the P-value approximately 0, we reject the Ho and concludethat the burning time for the control group of flares is less thanfor the group of flares with the new accelerant

Explanation / Answer

so are you stating that that there is not enough informationto conclude that the mean burning times for the two types of flaresdiffer? Thank you
