Maintenance Costs
Data was collected to investigate the relationship between the age and annual maintenance costs for a one particular car.The table below shows the costs over the life of a seven-year old car.
$$\begin{array} { | c | c }
\hline \text { Year } & \text { Annual Maintenance Casts } \
\hline 1 & \$ 150 \
\hline 2 & \$ 210 \
\hline 3 & \$ 450 \
\hline 4 & \$ 490 \
\hline 5 & \$ 510 \
\hline 6 & \$ 1590 \
\hline 7 & \$ 160 \
\hline
\end{array}$$
-In testing the hypotheses $H _ { 0 } : \beta _ { 1 } = 0$ vs. $\mathrm { H } _ { 1 } : \beta _ { 1 } \neq 0$ ,what is the rejection region at the 0.02 significance level?
What is the conclusion?
