the population mean body temp is 98.6 degrees with a standard deviation of 0.62 degrees F. Assume the distribution is approximately normal

a. what is the probability that a randomly selected person has a body temperature of more than 99 degrees using 4 decimal places

b. using a sample of 28 what is the probability that the mean body temperature is more than 99 degrees using 4 decimal places

c. in this example if the normal distribution was not assumed would the central limit theorum apply?
