Question

Trials in an experiment with a polygraph include

9696

results that include

2424

cases of wrong results and

7272

cases of correct results. Use a

0.010.01

significance level to test the claim that such polygraph results are correct less than

8080 %

of the time. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method. Use the normal distribution as an approximation of the binomial distribution.

Let p be the population proportion of correct polygraph results. Identify the null and alternative hypotheses. Choose the correct answer below.

A.

H0 :

pequals=0.200.20

H1 :

pless than<0.200.20

B.

H0 :

pequals=0.800.80

H1 :

pgreater than>0.800.80

C.

H0 :

pequals=0.800.80

H1 :

pnot equals?0.800.80

D.

H0 :

pequals=0.800.80

H1 :

pless than<0.800.80

Your answer is correct.

E.

H0 :

pequals=0.200.20

H1 :

pnot equals?0.200.20

F.

H0 :

pequals=0.200.20

H1 :

pgreater than>0.200.20

The test statistic is

zequals=nothing.

(Round to two decimal places as needed.)

Explanation / Answer

Answer

The correct option is part (c) i.e

Ho :P equals to 0.800

Ha: P not equals to 0.800

Hence

we failed to reject Null Hypothesis..

____________

Note:Please from next frame a proper question.

In this every part has two point in numericals which is blunder.
