Quizplus · Accepted Answer

Without the actual output and information on the sample size, it is impossible to calculate the confidence interval manually. However, the only way to estimate the confidence interval around the slope estimate is to use statistical software or a calculator. Therefore, without additional context, the best choice is to rely on the provided options and choose the one with the smallest range of values, which is D: 9.63 to 18.48.
