(a) What proportion of children aged 13 to 15 years old have soores on this test above 3? ? (NOTE: Please enter your answer in decimal form. For example, 45.23% should be entered as 04523.) Answer: 0_?1904 (5) Enter the score which marks the lowest 20 percent ofthe distribution. Answer: 30.84 ((2) Enter the score which marks the highest 10 percent of the distribution. Answer: M ? Because of the relatively high interest rates, most consumers attempt to pay otT 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.
