Because of the relatively high interest rates, mostconsumers attempt to pay off their credit card billspromptly. However, this is not always possible. Ananalysis of the amount of interest paid monthly by abank's Visa cardholders reveals that the amount isnormally distributed with a mean of 25 dollars and astandard deviation of 7 dollars. Please use z-scores withat least 3 decimal places.A. What proportion of the bank's Visa cardholders paymore than 29 dollars in interest?Proportion =B. What proportion of the bank's Visa cardholders paymore than 37 dollars in interest?Proportion =⠀C. What proportion of the bank's Visa cardholders payless than 14 dollars in interest?Proportion =D. What interest payment is exceeded by only 18% ofthe bank's Visa cardholders?Interest Payment =
