8. In a random sample of 250 customers at a fast food restaurant, 84 customers ordered a salad. If the restaurant typically has 1,000 customers in a day, how many customers will probably order a salad?

OpenStudy (anonymous):

we can have proportion here 84/250 = x/1000 then cross multiply... 250x=84000 x=336

OpenStudy (anonymous):

the probability is 42/125 times 1000 is 336
