The amount of money collected by a snack bar at a large university has been recorded daily for the past five years. Records indicate that the mean daily amount collected is 3900 and the standard deviation is 600.
 
  The distribution is skewed to the right due to several high volume days (including football game days). Suppose that 100 days were randomly selected from the five years and the average amount collected from those days was recorded. Which of the following describes the sampling distribution of the sample mean? A) normally distributed with a mean of 3900 and a standard deviation of 60
  B) normally distributed with a mean of 3900 and a standard deviation of 600
  C) normally distributed with a mean of 390 and a standard deviation of 60
  D) skewed to the right with a mean of 3900 and a standard deviation of 600

Question 2

Assume that blood pressure readings are normally distributed with a mean of 117 and a standard deviation of 9.6. If 144 people are randomly selected, find the probability that their mean blood pressure will be less than 119.
 
  A) 0.9938 B) 0.0062 C) 0.9998 D) 0.8615
