Question
You wish to test the following claim (Ha) at a significance level of a = 0.02.
Ho:p= 0.28
Ha:p< 0.28
You obtain a sample of size n = 308 in which there are 65 successful observations. For this test,
you should NOT use the continuity correction, and you should use the normal distribution as an
approximation for the binomial distribution.
What is the test statistic for this sample? (Report answer accurate to three decimal places.)
test statistic =
What is the p-value for this sample? (Report answer accurate to four decimal places.)
p-value =
The p-value is...
O less than (or equal to) a
O greater than a
This test statistic leads to a decision to...
O reject the null
O accept the null
O fail to reject the null
As such, the final conclusion is that...
O There is sufficient evidence to warrant rejection of the claim that the population proportion
is less than 0.28.
O There is not sufficient evidence to warrant rejection of the claim that the population
proportion is less than 0.28.
The sample data support the claim that the population proportion is less than 0.28.
OThere is not sufficient sample evidence to support the claim that the population proportion is
less than 0.28.
