Draw a graph to illustrate the Empirical Rule utilizing the symbols μ and σ. Include standardized values and explain

what is z-score?

Homework Answers

Answer #1

The Empirical rule for standard deviation is illustrated by diagram as:

This states that 68% of data lies within 1 standard deviation around the mean, 95% of data lies within 2 standard deviation around the mean and 99.7% of data lies within 99.7% around the mean.

This is often written as 68-95-99.7 rule.

In the image sahown above  μ is the mean and σ is the standard deviation.

Z-score is the standarized score of the dataset values and it is also number of standard deviiation values the dataset value is above or below the mean, which is calculated as:

The Empirical Rule is based on the standardized normal distribution. Describe how you could use the Empirical Rule to evaluate the distribution of scores on a national test. You are given the following information for the national test: (1) the population mean = 450 and (2) the population SD = 75. Second, based on the information given above, estimate the range of scores on this test. That is, estimate the low score and the high score on the test. Discuss...
