A school counselor surveyed 90 randomly selected students about the languages they speak. Of the students surveyed, 15 speak more than one language fluently. Based on these results, how many of the 1,800 students at the school can be expected to speak more than one language fluently? A.288 B.300 C.113 D.389

Respuesta :

Answer:

b

Step-by-step explanation:

Because the population is too large and it would be impractical to survey the whole population, a sample of the population is chosen to take part in the survey. This sample is taken as been representative of the whole population

Based on the sample, the fraction of students that speak more than one language fluently = 15/90= 0.166667

Population that would speak more than one language fluently = 0.166667 x 1800 = 300
