Suppose a normally distributed set of data has a mean of163 and a standard deviation of 17. Use the 68-95-99.7 rule(sometimes called the Empirical rule or the StandardDeviation rule) to determine the percentage of scores in thedata set expected to be between the scores 146 and 214.Answer =(Write your%3Danswer in decimal form, not percentage form. Forexample, if your percentage is 99%, enter 0.99, not 99.Keep all decimal places.)Caution: Using tables or Excel for this may produce awrong answer. Use the 68-95-99.7 rule.Check Answer
