Question

you wish to test the following claim (HaHa) at a significance
level of α=0.01α=0.01.

Ho:p=0.14Ho:p=0.14

Ha:p<0.14Ha:p<0.14

You obtain a sample of size n=709n=709 in which there are 94
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) αα
- greater than αα

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 0.14.
- There is not sufficient evidence to warrant rejection of the claim that the population proportion is less than 0.14.
- The sample data support the claim that the population proportion is less than 0.14.
- There is not sufficient sample evidence to support the claim that the population proportion is less than 0.14.

Answer #1

The statistical software output for this problem is :

Test statistics = -0.569

P-value = 0.2846

The p-value is greater than α

Fail to reject the null hypothesis .

There is not sufficient evidence to warrant rejection of the claim that the population proportion is less than 0.14.
