In your own words, describe the normal distribution and give at least three different types of data that are typically described as “normal.” Find a data set that follows the normal distribution. You may use the data from Week 2 if it follows a normal distribution. Make sure there is a minimum of 10 data points. Cite the data set using APA Style. Use the data to calculate the mean and standard deviation to construct a bell curve and answer the following questions:
What data value is associated with a z-score of 2.1?
What data value is associated with a z-score of -2.1?
What is the range of data values that would allow 68% of the data to fall within the mean?
An outlier refers to data points that lie beyond three standard deviations from the mean. Does this data set have any outliers? Explain why or why not.
Explain why 100% of the data does not always fall within three standard deviations of the mean.
