You wish to test the following claim (Ha) at a significance level of = 0.10.

Ho:p=0.27

Ha:p<0.27

You obtain a sample of sizen = 331 in which there are 85 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...

• less than (or equal to)
• greater than

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 less than 0.27.
• There is not sufficient evidence to warrant rejection of the claim that the population proportion is less than 0.27.
• The sample data support the claim that the population proportion is less than 0.27.
• There is not sufficient sample evidence to support the claim that the population proportion is less than 0.27.
