A test of H0: p = 0.4 versus Ha: p > 0.4 has the test
statistic z = 2.52.
Part A: What conclusion can you draw at the 5% significance
level? At the 1% significance level? (6 points)
Part B: If the alternative hypothesis is Ha: p ≠ 0.4, what
conclusion can you draw at the 5% significance level? At the 1%
significance level? (4 points) (10 points)

A statistician formulated a hypothesis test, specifying the
value of α, the hypotheses H0 and
Ha, and the data-collection and analysis procedures to
be used. Choose one of the following and write one or two sentences
justifying your choice:
α + β < 1
α + β = 1
α + β > 1
Any of the above might be true – more information about this
hypothesis test would be needed.

For a hypothesis test of H0: p = 0.65 against the
alternative Ha: p < 0.65, the z test statistic is
found to be -2.35. What can be said about his finding?
The finding is significant at both α = 0.05 and α = 0.01.
The finding is significant at α = 0.05 but not at α = 0.01.
The finding is significant at α = 0.01 but not at α = 0.05.
The finding is not significant at α...

≠0.6 , the test statistic equals 1.21. Find the P-value for this
test.

1. We want to test H0 : p ≥ 0.43 versus Ha : p < 0.43 . We
know that n = 500 and p = 0.3990 .
(a) What is the value of the test statistic? Round your test
statistic to 2 digits after the decimal point. (To get an answer
good to 2 digits, compute the standard error to 5 digits.)
(b) What is the p-value of the test ? Round your p-value to 3
digits after the...
