An orthodontist group has three financing packages, and each has a different service charge. He estimates that about 35% of the patients use the first plan which has a service charge of $100; 33% use the second plan which has a service charge of $200, and remaining use the third plan which has a service charge of $300. The standard deviation of the service charge, in dollars, is: 81.8 77.05 6691 5943.45

Suppose that the cost of annual tuition at colleges is normally distributed, with an average annual cost of $13,926.78. The standard deviation of tuition is $4,085.42. What proportion of colleges would be expected to have an annual tuition between the cost of College A with a tuition of $20,106.18 and College B with a tuition of $14,829.01?
Assume that human body temperatures are normally distributed with a mean of 98.19°F and a standard deviation of 0.64°F. a. A hospital uses 100.6°F as the lowest temperature considered to be a fever. What percentage of normal and healthy persons would be considered to have a fever? Does this percentage suggest that a cutoff of 100.6°F is appropriate? b. Physicians want to select a minimum temperature for requiring further medical tests. What should that temperature be, if we want only 5.0% of healthy people to exceed it? (Such a result is a false positive, meaning that the test result is positive, but the subject is not really sick.) Click to view page 1 of the table. Click to view page 2 of the table. a. The percentage of normal and healthy persons considered to have a fever is %. (Round to two decimal places as needed.) Does this percentage suggest that a cutoff of 100.6°F is appropriate? O A. No, because there is a large probability that a normal and healthy person would be…
