Gabby assigned a number to each of the 120 athletes at her school and
put the numbers in a box. She randomly chose 25 numbers and found that
10 athletes were female. Use this sample to make an inference about how
many athletes at Gabby's school are female.

Answer:

48

Step-by-step explanation:

[tex] \frac{10}{25} [/tex]

athletes are female. Now, we need to find what

[tex] \frac{x}{120} [/tex]

athletes are female.

10 ÷ 25 = 0.4

0.4 × 100 = 40 so

[tex] \frac{10}{25} = 40\%[/tex]

40% is the experimental probability for the number of female athletes in the sample. 40% of 120 should be about the number of female athletes in the whole school.

120 × 0.4 (or 40%) = 48.

You can infer that 48 athletes in the school are female.
