Scoring system: 1 point for correct answer and 2 points for the solution
A. Use the Table of Standard Normal distribution to determine corresponding probabilities of the following:
1. P(Z < -1.45)
2. P(0.5<Z < 2.33)
3. P(Z > 1.78)
B. X is a normally distributed random variable with a mean of 60 and a standard deviation of 8. Find the probabilities indicated by using the table.
1. P(X < 52)
2. P(48 < X < 64)
3. P(X > 57)
C. Solve the following problems by supplying the needed information.
The average number of calories in a 1.8-ounce chocolate bar is 230. Suppose that the distribution of calories is approximately normal with a standard deviation of 10.
1. Find the probability that a randomly selected chocolate bar will have less than 200 calories.
2. Find the probability that a randomly selected chocolate bar will have greater than 195 calories. 3. What is the percentage that a chocolate bar is randomly selected between 200 calories and 250 calories?
