1. Measures of Central Tendency. Please use the robbery data to calculate and report on the below. Mean: Median: Mode: 2. (5 points). Measures of Variability. Please use the robbery data to calculate and report on the below (Hint: treat all distributions as populations). Range: Variance: Standard Deviation: 3. (5 points). Z-scores. Please use the robbery data to calculate the Z-scores for the below values. 423: 603: 543: 582: 680: 4. (5 points). Standard Error of the Mean. What is the standard error of the mean for the following values sampled from the population of Seattle robberies: 426, 445, 603, 579, 543. (Also treat these five numbers as a population when calculating their standard deviation)? 5. Standard Error Z-scores & Area under the curve. What is the Z-score associated with the standard a. error of the mean you calculated in question 8? b. What percentage of a normal distribution would we expect to fall between the Z-score for the standard error of the mean and a Z-score of 0
