Suppose a normally distributed set of data has a mean of 100 and a standard deviation of 18. Use the 68-95-99.7 rule to determine the percent of scores in the data set expected to be between the scores 46 and 118. Give your answer in decimal form (for example, enter 0.68, NOT 68 or 68%) and keep all decimal places throughout your calculations and in your final answer.Suppose a normally distributed set of data has a mean of 100 and a standard deviation of 18.
