10. Which of the following statements are TRUE about the normal distribution? Check all that apply.

A z-score is the number of standard deviations a specific data value is from the mean of the distribution.
A data value with z-score = -1.5 is located 1.5 standard deviations below the mean.
The mean corresponds to the z-score of 1.
The area to the left of a z-score plus the area to the right of that same z-score will always equal 1.
The Empirical Rule only applies when a value is exactly 1, 2, or 3 standard deviations away from the mean.

2.For a standard normal distribution, find:

P(z < c) = 0.0604

Find c rounded to four decimal places.

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
