Answer:

d. -5.666 to -0.926

Step-by-step explanation:

Here a pivotal quantity is T = \frac{\hat{\beta_{1}}-\beta_{1}}{se(\hat{\beta_{1}})} where \beta_{1} is the true slope of the regression  equation (unknown), \hat{\beta_{1}} is its least square estimate and se(\hat{\beta_{1}})=1.097 is its estimated standard error. And T has t-distribution with n-2=15-2=13 degrees of freedom (n is the sample size). We have that \hat{\beta_{1}} = -3.30, and because we want the 95% confidence interval, we should use the 2.5th quantile of the t distribution with 13 df, this value is -2.16 and the 95% confidence intervale is given by \hat{\beta_{1}}\pm t_{0.025}se(\hat{\beta_{1}}), i.e., -3.30\pm (2.16)(1.097). Therefore, the 95% confidence interval explicitly is (-5.666, -0.926)

The answer has to be -9 because -9 + -4 is equal to -9 - 4, and that equals -13.
