Question
### Determining Statistical Measures for Ages of Shoppers The ages (in years) of a random sample of shoppers at a gaming store are shown below. We need to determine the range, mean, variance, and standard deviation of the sample data set. #### Sample Data Set of Ages: 12, 17, 23, 15, 21, 16, 20, 17, 14, 19 --- #### Range: The range is the difference between the maximum and minimum values in the data set. The problem requires us to determine: ``` The range is [ __ ] ``` To solve, simplify your answer. --- To calculate the other measures (mean, variance, and standard deviation), you can follow these steps: #### Mean: The mean (average) is calculated by summing all the ages and then dividing by the number of ages. #### Variance: Variance measures how far the ages are spread out from their mean. It is calculated by taking the average of the squared differences from the Mean. #### Standard Deviation: The standard deviation is the square root of the variance and provides a measure of how spread out the ages are from the mean.
