In a simple linear regression based on 28 observations, It is found that $b_1 = 7.4$ and $se(b_1) = 1.1$. Consider the hypotheses: (You may\nfind it useful to reference the ftable.)\n$H_0: b_1 \ge 10$ and $H_A: b_1 < 10$.\na-1. Calculate the value of the test statistic. (Negative value should be indicated by a minus sign. Round your answer to 3 decimal\nplaces.)\nTest statistic\na-2. Find the $p$-value.\n$\circ$ $p$-value $< 0.01$\n$\circ$ $p$-value $\ge 0.10$\n$\circ$ $0.05 \le p$-value $< 0.10$\n$\circ$ $0.01 \le p$-value $< 0.025$\n$\circ$ $0.025 \le p$-value $< 0.05$\nb. At the 5% significance level, what is the conclusion to the test?\n$\circ$ Do not reject $H_0$, we may conclude the slope coefficient is less than 10.\n$\circ$ Do not reject $H_0$; we may not conclude the slope coefficient is less than 10.\n$\circ$ Reject $H_0$; we may not conclude the slope coefficient is less than 10.\n$\circ$ Reject $H_0$; we may conclude the slope coefficient is less than 10.
