Suppose that po = 25% of a population has a certain characteristic and that a random sample of size n=300 is taken. Determine the probability that more than x = 84 people in the sample have the characteristic. i.e. calculate P(p > 84/300) = P(p > 0.28) . Enter your answer to 3 decimal places. Hint: You will need the normal table and use the formula p - Po Ро · N(0, 1) Po(1-po)

Question
Suppose that po = 25% of a population
has a certain characteristic and that a
random sample of size n=300 is taken.
Determine the probability that more
than x = 84 people in the sample have
the characteristic. i.e. calculate
P(p > 84/300) = P(p > 0.28)
. Enter your answer to 3 decimal
places.
Hint: You will need the normal table
and use the formula
p – Po
N(0, 1)
Po(1-po)
