A Gallup poll from 2016 showed that the share of Americans who are “extremely proud” to be American has been steadily decreasing since 2000 to 52% in 2016. Suppose the White House staff is concerned that the rating has fallen further. Let’s say that out of a random sample of 300 adults, 144 stated that they were “extremely proud” to be American. Using α = 0.05, answer the following questions.

a. State the null and alternative hypothesis.

b. Based on this sample, what conclusions can be drawn for this test?

c. Determine the p-value for this test and interpret its meaning.

d. How would the conclusions be affected if the White House chose to use α = 0.10 rather than α = 0.05.
