Because of the relatively high interest rates, most consumers attempt to pay off their credit card bills promptly. However, this is not always possible. An analysis of the amount of interest paid monthly by a bank's Visa cardholders reveals that the amount is normally distributed with a mean of 25 dollars and a standard deviation of 6 dollars. A. What proportion of the bank's Visa cardholders pay more than 27 dollars in interest? Proportion = B. What proportion of the bank's Visa cardholders pay more than 35 dollars in interest? Proportion = C. What proportion of the bank's Visa cardholders pay less than 16 dollars in interest? Proportion = D. What interest payment is exceeded by only 19% of the bank's Visa cardholders? Interest Payment =(1 point) Assume that the monthly worldwide average number of airplaine crashes of commercial airlines is 2.2. What is the probability that there will be (a) less than 2 such accidents in the next month? 0103 (b) more than 4 such accidents in the next 2 months? (c) exactly 7 such accidents in the next 5 months?(1 point) Consider a normal distribution curve where 95-th percentile is at 11 and the 20-th percentile is at 7. Use this information to find the mean, , and the standard deviation, o , of the distribution. a) != b) 0 =(1 point) The physical fitness of an athlete is often measured by how much oxygen the athlete takes in (which is recorded in milliliters per kilogram, ml/kg). The mean maximum oxygen uptake for elite athletes has been found to be 70 with a standard deviation of 5.6. Assume that the distribution is approximately normal. (a) What is the probability that an elite athlete has a maximum oxygen uptake of at least 55 ml/kg
