You obtain a sample of size n=124n=124 in which there are 95 successful observations. Assume the normal distribution applies.

What is the critical value for this test? (Report answer accurate to two decimal places.)
critical value = ±±

What is the test statistic for this sample? (Report answer accurate to two decimal places.)
test statistic =

The test statistic is...

in the critical region
not in the critical region

This test statistic leads to a decision to...

reject the null
accept the null
fail to reject the null

As such, the final conclusion is that...

There is sufficient evidence to warrant rejection of the claim that the population proportion is not equal to 0.63.
There is not sufficient evidence to warrant rejection of the claim that the population proportion is not equal to 0.63.
The sample data support the claim that the population proportion is not equal to 0.63.
