1. The following frequency distribution which shows the savings held by a random selection of American 20 to 30 year olds. Savings Frequency 50-$19,999 344 $20,000-$39,999 98 $40,000-$59,999 52 $60,000-$79,999 19 $80,000-$99,999 13 $100,000-$119,999 6 a . Using the table below calculate the mean of this distribution Savings Frequency Class Midpoint Frequency X Class Midpoint $0-$19,999 344 (0 + 20000)/2 = 10000 344 X 10000 = $3,440,000 $20,000-$39,999 E E Answer: b. Calculate the approximate median of this distribution: Answer: c. Is this distribution skewed right, skewed, left or roughly symmetric? (circle one). Explain how you know. d.
