A zoologist selected 12 black bears in a Canadian habitat at random to examine the relationship between the age in years, x, and the weight in tens of pounds, y. The 95 percent confidence interval for estimating the population slope of the linear regression line predicting weight in tens of pounds based on the age in years is (7.0, 18.4). Assume that the conditions for inference for the slope of the regression equation are met. Which of the following is the correct interpretation of the confidence level
