Professor York randomly surveyed 240 students at Oxnard University and found that 150 of the students surveyed watch more than 1
BaLLatris [955]

Answer:

1727 students

Step-by-step explanation:

Here we have the formula for sample size given as

n = \frac{p(1-p)z^2}{ME^2}

Where:

p = Mean

ME = Margin of error = 3

z = z score

Therefore, we have

p = 150/240 = 0.625

z  at 99 % = 2.575

ME = \pm3%

Therefore n = \frac{0.625(1-0.625)2.575^2}{0.03^2} = 1726.73

The number of students Professor York have to sample to estimate the proportion of all Oxnard University students who watch more than 10 hours of television each week within ±3 percent with 99 percent confidence = 1727 students.
