1. Sample data in the textbook suggest that for the body temperatures (in degrees Fahrenheit) of normal and healthy adults, = 98.20 and = 0.62, and the temperatures have a normal distribution. Use those parameters for the following questions.

a. If someone is randomly selected, find the probability that the body temperature is at least 98.00. __________

b. If someone is randomly selected, find the probability that the body temperature is greater than 99.00. __________

c. If someone is randomly selected, find the probability that the body temperature is between 97.00 and 98.00. __________

d. If someone is randomly selected, find the probability that the body temperature is below 100.00. __________

e. If 16 people are randomly selected, find the probability that their mean body temperature is below 98.50. __________

f. If 100 people are randomly selected, find the probability that their mean body temperature is between 98.15 and 98.50. __________

g. Find P90 (the 90th percentile), which is the temperature separating the bottom 90% from the top 10%. __________

h. Find P10 (the 10 th percentile), which is the temperature separating the bottom 10% from the top 90%. __________ (
