Answer:

The sample size should be 273 students

Step-by-step explanation:

Here Raina wants to use 90% interval then

ME = z. SE

SE = s d/√n at end

ME/z   = s d/√n

n={z.sd/ME)²

Z = 1.65    =>due to  90%confidence interval

ME= 24

sd=250

putting these value in the question we get 273 students
