A middle school has 470 students. Regina surveys a random sample of 40 students and finds that 28 have cell phones. How many students at the school are likely to have cell phones?
so from that i think the formula would be [tex] \frac{x}{470} = \frac{28}{40} [/tex] so then you find "x" by multiplying 470 x 28 which equals 13,160. Then you divide 13,160 by 40 which equals 329. X=329 329 students are likely to have phones
