Question

In 1997, a survey of

800800

households showed that

132132

of them use e-mail. Use those sample results to test the claim that more than 15% of households use e-mail. Use a 0.05 significance level. Use this information to answer the following questions.

a. Which of the following is the hypothesis test to be conducted?

Upper H 0 : p equals 0.15H0: p=0.15

Upper H 1 : p not equals 0.15H1: p≠0.15

Upper H 0 : p equals 0.15H0: p=0.15

Upper H 1 : p less than 0.15H1: p<0.15

Upper H 0 : p greater than 0.15H0: p>0.15

Upper H 1 : p equals 0.15H1: p=0.15

Upper H 0 : p equals 0.15H0: p=0.15

Upper H 1 : p greater than 0.15H1: p>0.15

Your answer is correct.

Upper H 0 : p less than 0.15H0: p<0.15

Upper H 1 : p equals 0.15H1: p=0.15

Upper H 0 : p not equals 0.15H0: p≠0.15

Upper H 1 : p equals 0.15H1: p=0.15

b. What is the test statistic?

zequals=nothing

(Round to two decimal places as needed.)

What is it the P-Value?
