Question

students watched in the last three months. Use this dot plot to answer the question below.

number of movies
0/2 1/4 2/6 3/4 4/2 5/2

What percent of the students watched at least 3 movies?

To answer this question, we must first count the total number of data points (add up all of the dots). Then, determine the number of data points that meet the criteria (less than, greater than, more than, at least, etc.). What do those inequalities mean? Take the value you found and divide it by the total number of data points in the dot plot. Multiply this number by 100 to find your percentage.

40%

Answer 1

To find the correct answer, we first need to count the total number of data points in the dot plot. Adding up all the dots, we get:

0 + 2 + 4 + 6 + 4 + 2 + 2 = 20

Next, we need to determine the number of students who watched at least 3 movies. From the dot plot provided, we see that there are 6 students who watched 3 movies, 4 who watched 4 movies, and 2 who watched 5 movies. So the total number of students who watched at least 3 movies is:

6 + 4 + 2 = 12

To find the percentage of students who watched at least 3 movies, we divide the number of students who watched at least 3 movies by the total number of data points and then multiply by 100:

(12/20) * 100 = 60%

Therefore, the correct answer is:

60%
