Scenario 2: For normally distributed data with a mean of 20 and a standard deviation of 4, 80% of the data will be plus or minus X from the mean. Find X. i.e., if your answer is that 80% of the data falls within the range of 10 - 30, your X would be "10" because that range is represented as 20 +/- 10. (hint: Group Workshop Significance Testing will help) Your answer should be in decmal format out to one decimal place (e.g., 0.0)
