Chapter 7.3, Problem 8E

a.

To determine

Find the least-squares estimates ${\beta }_0$ and ${\beta }_1$.

b.

To determine

Check whether there is evidence to conclude that the null hypothesis $H_0:{\beta }_0=0$ is rejected.

c.

To determine

Check whether there is evidence to conclude that the null hypothesis $H_0:{\beta }_1=1$ is rejected.

d.

To determine

Check whether the data provide sufficient evidence to conclude that the prediction method is not accurate.

e.

To determine

Find the 95% confidence interval for the mean prediction when the true roughness is 0.8μ m.

f.

To determine

Check whether the data provide sufficient evidence to conclude that the given claim is false.
