Question

You wish to test the following claim at a significance level of α=0.002

H0:p=0.67
H1:p<0.67

You obtain a sample of size n=683n=683 in which there are 420 successful observations.

What is the critical value for this test? (Report answer accurate to 2 decimal places.)

What is the test statistic for this sample? (Report answer accurate to 3 decimal places.)

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 conclude that the population proportion is less than 0.67.
there is not sufficient evidence to conclude that the population proportion is less than 0.67.
there is sufficient evidence to conclude that the population proportion is equal to 0.67.
there is not sufficient evidence to conclude that the population proportion is equal to 0.67.
