Test the hypothesis using the​ P-value approach. Be sure to verify the requirements of the test.

H0​: p=0.6 versus H1​: p>0.6

n=250; x=160​, a=0.01

Is np 0 ( 1−p0) ≥​10?

Yes or NO?

Use technology to find the​ P-value.

​P- value=________

​(Round to three decimal places as​ needed.)

__________the null​ hypothesis, because the​ P-value is __________ than α.

H0 : p = 0.6 versus H1 : p > 0.6

n = 250

x = 160

sample proportion, p' = x/n = 160/250 = 0.64

p0 = 0.6

q0 = 1-p0 = 1-0.6 = 0.4

n p0 (1-p0) = 250 0.6 0.4 = 60 >10

The test statistic is,

P- Value = 0.098

Here = 0.01

Accept the null hypothesis, because the P-value is greater than .
