Yes, because the amount of the loan is greater than the upper bound of the 95% interval O C. No, because the amount of the loan is less than the midpoint of the 95% interval O D. No, because the amount of the loan is greater than the upper bound of the 95% interval O E. Yes, because the amount of the loan is greater than the midpoint of the 95% interval OF. Yes, because the amount of the loan is contained in the 95% interval Screenshot 2023-04-12 at 6.... . Q Q 2 .
