What is the mean of the standard normal distribution? What is the standard deviation of the standard normal distribution? Choose the correct answer below. A. The mean and standard deviation have the values of \( \mu=0 \) and \( \sigma=1 \). The mean and standard deviation have the values of \( \mu=1 \) and \( \sigma=1 \). The mean and standard deviation have the values of \( \mu=1 \) and \( \sigma=0 \). D. The mean and standard deviation have the values of \( \mu=0 \) and \( \sigma=0 \).

A set of exam scores is normally distributed with a mean \( =74 \) and standard deviation \( =8 \). \( 95 \% \) of the data values lie between 58 \( \% \) of the exam scores are between 66 and 74 . \( \% \) of the exam scores are between 74 and 90 . \% of the exam scores are greater than or equal to 66 .

Which of the following statements are TRUE about the Normal Distribution? Check all that apply. The graph of the Normal Distribution is bell-shaped, with tapering tails that never actually touch the horizontal axis. \( 50 \% \) of the data values lie at or above the mean. about \( 95 \% \) of all data values lie within 1 standard deviation of the mean. The mean, median and mode are all equal and occur at the center of the distribution. Data values are spread evenly around the mean. Data values farther from the mean are less common than data values closer to the mean.
