The A hypothesis test for a population proportion p is given
below:
H0: p = 0.10
Ha: p ≠ 0.10
Sample size n = 100 and sample proportion pˆ = 0.15. z-statistic =
?
Calculate the p-value for a hypothesis test of a proportion. The
hypotheses are H0: p=.5, H1: p>.5 and the
test statistic is z = 1.02.
Round your answer to 4 decimal places
Below there is information for a 1 sample proportion hypothesis
test:

What is the smallest value of the test statistic that would
provide enough evidence to reject the null hypothesis? [3]

1)
You are asked the conduct the following hypothesis test
concerning a population proportion:
H0: prop = 0.27
HA: prop < 0.27
You draw a sample of size 248 from the population. There are 51
individuals in the sample who satisfy the criteria in which we are
interested. Calculate the p-value for this test.
Round your answer to 4 decimal places.

You are asked the conduct the following hypothesis test
concerning a population proportion:
H0: prop = 0.43
HA:...
If we were to conduct a hypothesis test to test if a population
proportion of a certain event is 0.2 versus the alternative that it
is greater than 0.2 and we sampled 100 people, what would the
probability of a Type I Error be if we were to use the arbitrary
decision rule to reject Ho if more than 30 units in the sample had
the event (not the way we tested hypotheses in class)? What would
the probability of...
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...
