Question

An cmploycc claims that drinking beer has no effect on the amount of time it takes for him to perform a particular task. The following data show how many scconds he took to perform the task after consuming varlous quantitles of beer, measured in ounces: x-c(,12,24,36,48,60,72)y-c2.8,50.7,59.9,75.4,59.1,84.9,68.5); Consider the model Yi = 0+1+ where E's are iid N(0, 2) =252,y = 461.3,2= 13104572 = 31180.57,.cy= 176232,(s-p" = 4032,(y-y)2 = 780.9 (r-5)(y-1) = 1016.4,U=30+B1%,(y-!)2=524.6825,Se=1(104.9365) = 10.24385,R2 = 0.3281

Explanation / Answer

Using minitab

Two-Sample T-Test and CI: x, y

Two-sample T for x vs y

N Mean StDev SE Mean
x 7 36.0 25.9 9.8
y 7 65.9 11.4 4.3

Difference = (x) - (y)
Estimate for difference: -29.9
90% lower bound for difference: -44.9
T-Test of difference = 60 (vs >): T-Value = -8.40 P-Value = 1.000 DF = 8

See P -value is greter than 0.10 so we fail to Reject Ho means it 0
