Final answer:

Without the necessary statistics from the regression output, it is impossible to determine the 99 percent confidence interval for the educ coefficient. One needs the point estimate, standard error, and the appropriate z-value or t-value to calculate the interval.

Step-by-step explanation:

The question pertains to constructing a 99 percent confidence interval for the educ coefficient in a regression analysis. Without the specific output from the regression analysis, such as the standard error of the estimate and the point estimate of the coefficient, we cannot determine the actual confidence interval. To create a 99 percent confidence interval, one would typically use the point estimate, the standard error associated with that estimate, and the appropriate z-value or t-value that corresponds to the desired level of confidence.

A higher confidence level, such as 99 percent versus 95 percent, results in a wider interval as it has to include a greater portion of the distribution. This interval suggests that we can be 99 percent confident that the true population parameter lies within this range. The correct answer to this question is not provided because the necessary statistics to compute the range are missing. However, it is essential to understand the process and the reasoning behind constructing confidence intervals.
