Part 3

Are you more likely to randomly select 1 woman with a height less than

66.2

inches or are you more likely to select a sample of

women with a mean height less than

66.2

inches? Choose the correct answer below.

It is more likely to select a sample of

women with a mean height less than

66.2

inches because the sample of

has a lower probability.

It is more likely to select 1 woman with a height less than

66.2

inches because the probability is higher.

It is more likely to select 1 woman with a height less than

inches because the probability is lower.

It is more likely to select a sample of

women with a mean height less than

66.2

inches because the sample of

has a higher probability.

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.
