You may need to use the appropriate technology to answer this question. Consider the data. $x_i$ | 3 | 12 | 6 | 20 | 14 $y_i$ | 70 | 40 | 55 | 10 | 10 (a) Compute the mean square error using equation $s^2 = MSE = \frac{SSE}{n-2}$. (Round your answer to two decimal places.) (b) Compute the standard error of the estimate using equation $s = \sqrt{MSE} = \sqrt{\frac{SSE}{n-2}}$. (Round your answer to three decimal places.) (c) Compute the estimated standard deviation of $b_1$ using equation $s_{b_1} = \frac{s}{\sqrt{\sum x_i^2 - \frac{(\sum x_i)^2}{n}}}$. (Round your answer to three decimal places.) (d) Use the $t$ test to test the following hypotheses ($\alpha = 0.05$): $H_0: \beta_1 = 0$ $H_1: \beta_1 \ne 0$ Find the value of the test statistic. (Round your answer to three decimal places.) Find the $p$-value. (Round your answer to four decimal places.) $p$-value = State your conclusion. $\circ$ Do not reject $H_0$. We conclude that the relationship between $x$ and $y$ is significant. $\circ$ Reject $H_0$. We conclude that the relationship between $x$ and $y$ is significant. $\circ$ Reject $H_0$. We cannot conclude that the relationship between $x$ and $y$ is significant. $\circ$ Do not reject $H_0$. We cannot conclude that the relationship between $x$ and $y$ is significant. (e) Use the $F$ test to test the hypotheses in part (d) at a 0.05 level of significance. Present the results in the analysis of variance table format. Set up the ANOVA table. (Round your values for MSE and $F$ to two decimal places, and your $p$-value to three decimal places.)
