The "log" in this question refers to the natural log, and the "sqrt" below refers to the square root. Suppose we create a model in R using the model lm(sqrt(Y) ~ log(X)) We use the predict() command in R to compute the 95% confidence interval for prediction when X = 100 We obtain the output below. fit lwr upr 8 7 9 We conclude that when X = 100, we're 95% confident that the value of Y is between Question 7 options: 7^2 and 9^2 sqrt(7) and sqrt(9) between log(7) and log(9) between e^(7) and e^(9) between 7 and 9
