2. Use the range rule of thumb to estimate the standard deviation for the following data set: $$ 12,4,5,23,4,7,9,10,13,13,22,20,6 $$ $$ \begin{array}{1} 44,5,23,4,7,9,10,13,13,22,20 ,6 \\ \text { Use...

Extracted text: 2. Use the range rule of thumb to estimate the standard deviation for the following data set: $$ 12,4,5,23,4,7,9,10,13,13,22,20,6 $$ $$ \begin{array}{1} 44,5,23,4,7,9,10,13,13,22,20 ,6 \\ \text { Use the formula for standard deviation to find the actual standard } \end{array} $$ 3. Use the formula for standard deviation to find the actual standard deviation of the sample data in number 2 above. $$ 3=\frac{23-4}{4}=4.75 $$ 4. Using the data from question #2 and the range rule of thumb, determine if any of the data values would be considered "unusual." Why or why not? SP.AS306
