If it is appropriate to do so, use the normal approximation to
the p^ p^ -distribution to calculate the
indicated probability:
Standard Normal Distribution Table
n=80,p=0.715n=80,p=0.715
P( p̂ > 0.75)P( p̂ > 0.75) =
Enter 0 if it is not appropriate to do so.
Please provide correct answer. thanks

5) If it is appropriate to do so, use the
normal approximation to the p^-distribution to calculate
the indicated probability:
n=60,p=0.40n=60,p=0.40
P( p̂ < 0.50)= ?
Enter 0 if it is not appropriate to do so.

1. Normal Approximation to Binomial Assume
n = 10, p = 0.1.
a. Use the Binomial Probability function to compute the P(X =

b. Use the Normal Probability distribution to approximate the
P(X = 2)
c. Are the answers the same? If not, why?

Normal Approximation to Binomial
Assume n = 100, p = 0.4.
Use the Binomial Probability function to compute the P(X =

Are the answers the same? If not, why?

Determine if the conditions required for the normal
approximation to the binomial are met. If so, calculate the test
statistic, determine the critical value(s), and use that to decide
whether there is sufficient evidence to reject the null hypothesis
or not at the given level of significance.

Do you take the free samples offered in supermarkets? About 64% of
all customers will take free samples. Furthermore, of those who
take the free samples, about 37% will buy what they have sampled.
