Draw a rough sketch of the income distribution in the space provided, with clearly labelled axes. Indicate the approximate positions of the mean, median and mode. (5 marks) 2. Describe the distribution as symmetric or positively or negatively skewed. (1 mark) 3. If no two families earned exactly the same amount, can we determine how many families in the sample earned less than $55,126? Why or why not? (2 marks) 4. Based on the given data, can we determine the number of families that earned more than $41,8987 Why or why not? (2 marks)
