The rule that describes the percentage of data within 1, 2, and 3 standard deviation of the mean is called the [rule]. O Standard Rule O Empirical Rule Percentage Rule O Monarchy Rule

Using the data below (assume the data comes from a population) 5,8,14,6,21,11,9,10,18,2 A.  Calculate the three measures of central tendency B. Calculate the standard deviation of the data and what the variance is C. Draw a box plot D. Using the IQR X 1.5(Interquartile Range), Can you identify any outliers in the data?

Midterm exam scores are normally distributed with a mean of 75 and a standard deviation of 6. If the exam is given to 10,000 students, we would expect   No one to receive a score of 87 No one to have received a score below 63 Half the scores to fall between 70 and 83 NO Half the scores to fall between 64 and 88 Just over one third of the scores to fall between 75 and 81

Statistics that describe typical scores are called:   Select one: a. Models b. Standard deviations c. Z scores d. Measures of central tendency

Details The scores on a standardized test are normally distributed with a mean of 90 and standard deviation of 8. What test score is 4 standard deviations below the mean?

The coefficient of variation CV describes the standard deviation as a percent of the mean. Because it has no​ units, you can use the coefficient of variation to compare data with different units. Find the coefficient of variation for each sample data set. What can you​ conclude?

z Scores LeBron James, one of the most successful basketball players of all time, has a height of 6 feet 8 inches, or 203 cm. Based on statistics from Data Set 1 “Body Data” in Appendix B, his height converts to the z score of 4.07. How many standard deviations is his height above the mean?
