The graph above is a scatter plot with 49 points. The 49 points represent the number of elementary and high schools in 48 U.S. states and the District of Columbia (the numbers of schools in California and Texas are too large to appear on a graph of this scale). The dotted line represents a regression line. 
 For each blank, select the answer choice that correctly completes the statement according to the information in the graph.

3. Approximately  GRAPH_1_PLACEHOLDER  percent of the 49 states (including the District of Columbia) represented in the graph have fewer than 500 high schools.

4. The point corresponding to the greatest total number of schools also corresponds to the greatest number of  GRAPH_2_PLACEHOLDER .

as.hish404 · Answer

Look at the number of high schools on the graph. Draw an imaginary line between 400 and 600 on the Y-axis; 
above that line, there are 13 points, indicating 13 states with more than 500 high schools. 
The total number of states represented in the graph with fewer than 500 high schools =  total - (more than 500) => 49 - 13 = 36

Now, for Question 1: What percent of the 49 states (including the District of Columbia) represented in the graph have fewer than 500 high schools? =>  (36 * 100) / 49 = 73.47
 
 approximately 75 percent.

Highest Total Number of Schools is in point where (too the top right most corner)
Elementary School = 3,200
High School = 1,200
Total Schools = 4,400 (Approx.)

Here it has the highest number of Elementary Schools

cheshire · Answer

>If you count the amount of points above y = 500 (500 highschools) it'll be around 25% of the total points.
>the question asks for the points below y = 500 so the answer will be 75%

ReetArora · Answer

But still how does it shows greater no. of Elementary schools corresponds to greater no. of total schools?

cheshire · Answer

I mean more schools = more schools. Elementary schools count as schools so the more of them there are, the more total schools exist.

Q3.  By eyeballing the scatter plot, most points are below the horizontal line at 500. That’s roughly  3/4 of the states , i.e.  75% . 
 Q4.  Total number of schools = elementary + high. The farthest right point (largest total) is also the one with the  greatest number of elementary schools .
