One graph in the figure represents a normal distribution with mean u= 15 and standard deviation o = 2. The other graph represents a normal distribution with mean u=11 and standard deviation o = 2. Determine which graph is which and explain how you know. A B 11 15 ... Choose the correct answer below. O A. Graph A has a mean of u = 15 and graph B has a mean of u = 11 because a larger mean shifts the graph to the right. O B. Graph A has a mean of u = 11 and graph B has a mean of u= 15 because a larger mean shifts the graph to the left. O C. Graph A has a mean of u = 11 and graph B has a mean of u = 15 because a larger mean shifts the graph to the right. O D. Graph A has a mean of u = 15 and graph B has a mean of u = 11 because a larger mean shifts the graph to the left.

Lesson 7: Understanding the Normal Distribution II. PRETEST: Task 1: TRUE OR FALSE, Write TRUE if the given statement is true. Otherwise, write FALSE. 1. A normal random variable is a random variable X whose distribution has the shape of a normal curve. 2. The total area of the normal probability distribution is 100. 3. All observations of any normal random variable X with the mean u and standard deviation o to a new set of observations of another normal random variable Z with mean u = 0 and standard deviation o = 1. 4. The value of a probability is a number from 0 to 1. 5. The area of a region between z = 0 and z = 2 is 0.4772. IV. EVALUATION: Direction: Fill in the blanks with the appropriate word or phrase to make the following illustration on normal random variable meaningful. 1. A random variable X whose distribution has the shape of a normal curve called 2. The shape of the normal curve is with the total area of 3. The center of the normal curve is the with the value of if it is…
