Question 857313: n is the sample size
p is the population proportion
p-hat is the sample proportion
Use the Central Limit Theorem to find the Proportion probability.
n = 101, p = 0.86, P (p-hat < 0.80)

You can put this solution on YOUR website! n is the sample size
p is the population proportion
p-hat is the sample proportion
Use the Central Limit Theorem to find the Proportion probability.
n = 101, p = 0.86, P (p-hat < 0.80)
------
z(0.80) = (0.80-0.86)/sqrt[0.86*0.14/101] = -1.7378
----
P(p-hat < 0.8) = P(z < -1.7378) = normalcof(-100,-1.7378) = 0.0411
