Kendra wants to know the average height of first-year high school students in her town. She randomly picked 25 male and 25 female students from each of the 10 high schools in her town. From the data she collected, she concluded that the average height of first-year high school students in her town is 5 feet, 7 inches.

Question

How many students in total were included in her representative sample?

Answer 1

There were 25 male students and 25 female students from each of the 10 high schools, so the total number of students in the sample is:

25 + 25 = 50 students per high school
50 x 10 = 500 students

Therefore, there were a total of 500 students included in Kendra's representative sample.
