Construct a 95% confidence interval for $\beta_1$, the regression slope coefficient.
The 95% confidence interval for $\beta_1$, the regression slope coefficient, is (-10.15, -1.73). (Round your responses to two decimal places.)
The t-statistic for the two-sided test of the null hypothesis $H_0$: $\beta_1$ = 0 is -2.7981. (Round your response to four decimal places.)
Note: Assume a normal distribution.
The p-value for the two-sided test of the null hypothesis $H_0$: $\beta_1$ = 0 is 0.0052. (Round your response to four decimal places.)
Do you reject the null hypothesis at the 1% level?
A. Yes, because the t-statistic is less than 2.58.
B. Yes, because the t-statistic is greater than 2.58.
C. Yes, because the p-value is less than 0.01.
D. No, because the p-value is greater than 0.01.
The p-value for the two-sided test of the null hypothesis $H_0$: $\beta_1$ = -5.7 is (Round your response to four decimal places.)
