We are given that P = population proportion of persons 20-30 years old that hold license degrees (unknown) and we are asked to test
H0: p≤0.67 versus H1: p>0.67
The observed sample proportion is pˆp^ = 61/79 = 0.772 from a random sample of size 79.
compute the following:
a) P- value of the test
b) Probability of making Type II error and the power of this test at p= 0.87

The sample proportion p-bar provides an estimate for the
population proportion p. The sampling distribution of the sample
proportion is the probability distribution of the sample
proportion.
Consider a population with a proportion p = 0.60, from which a
sample of size n = 200 is drawn. What is the sampling distribution
of the sample proportion p-bar?
Calculate the following probabilities using the distribution
above:
P(? < 0.5)
P(? > 0.7)
P(0.5 < ? < 0.7)

Let p denote the population proportion of years in
which the daytime temperature in New York on Valentine's Day
(February 14) is below the freezing point. It is known that in 98
out of the most recent 120 years, the daytime temperature in New
York on February 14 was below the freezing point. Assume that this
data represents a random sample from the population.
a) Construct a 99% confidence interval for p. Given the
following R output:
qt(0.01, df=119, lower=F)...
