Question

If you flip a coin 100 times, the number of heads you will get is normally distributed (or very close to being normally distributed), with a mean of 50 and a standard deviation of 5. A man who is seven feet tall would be about as unlikely as flipping a coin 100 times and getting how many heads?

Group of answer choices

A. 64

B. 73

C. 92

D. We cannot compare coin flips with height, because everybody has a certain height, but coin flips are uncertain.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
