Answer 1

Answer #1

4.6)

dbar = 3.21

s(dbar) = 5.2330

SE = s(dbar)/sqrt(n)

= 5.2330/sqrt(9)

= 1.7443

Test Statisitcs, t = dbar/SE

= 3.21/1.7443

= 1.8402

degrees of freedom = n-1 = 8

p-value = 0.0515

As p-value is greater than the significance level of 0.05, we fail to reject the null hypothesis.
