Question 9 :
Hypothesis Test: Decision
A hypothesis test gives a p-value of 0.05. If the significance level is set at 0.05, the results are said to be:
not statistically significant
statistically significant
inconclusive because the p-value is not smaller nor larger than the significance level

statistically significant
Explanation:
Results are statistically significant if the p-value is less than or EQUAL TO the significance level.

Think about the test statistic value:
Consider the formula for the z test statistic. Although its exact value cannot be computed without
knowing the actual sample size
n,
it can be determined that the resulting test statistic value will be:

Question 10 Background :
An Unusual P-Value
Suppose a researcher collected data to assess if a “majority” of all residents of a particular city were in favor of a newly proposed city
ordinance. Her hypotheses are H
:
p
= 0.5 versus H
:
p
> 0.5. A large enough random sample of residents was obtained and the resulting
sample proportion was 0.41.
