Answer 1

Ans:

Test statistic:

t=((114.5-129.6)-(-10))/SQRT((5.06^2/5)+(5.37^2))

t=-0.88

df=5+5-2=8

p-value=tdist(0.88,8,1)=0.203

As,p-value>0.01,we fail to reject the null hypothesis.

Fail to reject H₀.The data does not suggest that the difference between mean stopping distances is less than -10.
