Solution

The text you provided contains multiple questions. Here are the answers:

Question 1: The student who used a method of display that was not appropriate for the data is Ali. Line graphs are used to display data that changes over time, not categorical data like height, years at the club, and age.

Question 2: Five possible prices for the houses could be 400,000,400,000, 600,000, 700,000,700,000, 800,000, and 1,000,000.Thissetofpriceshasarangeof1,000,000. This set of prices has a range of 600,000 (the difference between the highest and lowest prices) and a median of $700,000 (the middle value when the prices are arranged in ascending order).

Question 3: Abdel will not get a correct answer continuing with this procedure. He is dividing the original price by 30, then multiplying by 100, which is not the correct way to calculate a 30% increase. The correct calculation would be to multiply the original price by 0.30 (which represents 30%), then add that amount to the original price.
