Question

The test statistic of z = 1.92 is obtained when testing the claim that p+0.354. a. Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed. b. Find the P-value. c. Using a significance level of a = 0.01, should we reject He or should we fail to reject Ho?

P-value = (Round to three decimal places as needed.) c. Choose the correct conclusion below. O A. Fail to reject Ho. There is sufficient evidence to support the claim that p*0.354. OB. Reject Ho. There is sufficient evidence to support the claim that p*0.354. O C. Reject Ho. There is not sufficient evidence to support the claim that p*0.354. D. Fail to reject Ho. There is not sufficient evidence to support the claim that p+0.354.

Answer 1

Answer:

claim is P$\neq$ 0.354

a)

This is two tailed test.

b)

test statistics: z= 1.92

p-value = 2 * ( 1- p( z < 1.92 ))

using normal z table we get,

p(z< 1.92) = 0.9726

p-value = 2 * ( 1 - 0.9726 )

p-value = 0.0548

P-Value = 0.055

c)

decision rule is

Reject Ho if ( p-value ) < $\alpha$

here (p-value = 0.055 ) > 0.01

hence,

D.fail to reject Ho, There is not sufficient evidence to support the claim that p$\neq$ 0.354
