1. Which of the following statements are true? Multiple choice. The normal distribution is skewed It is necessary to know the mean and the standard deviation to construct a specific normal distribution Each combination of mean and standard deviation defines a unique normal distribution. The normal distribution extends to infinity in any direction from the mean. The normal distribution is measured on a discrete scale. The total area under the curve is equal to 1.0 The probability that a random variable has a value between any two points is equal to the area under the curve between those two points.

11. Which of the following is not true about continuous random variables? A) They have an infinite set of values. B) The area under each of the curves represents probabilities. C) The entire area under each of the curves equals 1. D) Some may be described by the Normal distribution. E) They can only be integer values. 12. Which of the following statements is not true for a normal probability distribution? A) The area under the curve is 1. B) It is symmetrical. C) The midpoint is also the mean. D) Ninety-five percent of the area under the curve lies within ± one standard deviation of the mean.
Qbs E.
Choose all the statements that are true. When the mean of the normal distribution decreases from 10 to 5 the normal curve shifts to the right. When the mean of the normal distribution decreases from 10 to 5 the normal curve shifts to the left. When the standard deviation of a normal distribution decreases from 6 to 2 it becomes flatter. When the standard deviation of the normal goes from 4 to 8 it does not affect the shape of the curve. When the standard deviation of a normal distribution decreases from 6 to 2 it becomes taller.

Consider two normal distributions, one with mean -4 and standard deviation $3,$ and the other with mean -4 and standard deviation $6 .$ Answer true or false to each statement and explain your answers. a. The two normal distributions have the same shape. b. The two normal distributions are centered at the same place.
