The test statistic of zequals2.03 is obtained when testing the claim that pnot equals0.615. 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 alphaequals0.01​, should we reject Upper H 0 or should we fail to reject Upper H 0​?

complete a through c

Answer 1

Solution:

Given that,

z= 2.03

p $\neq$ 0.615

a)

This is a two tailed test.

b)

P-value = 2*P(Z > z )

= 2*(1 - P(Z < 2.03))

= 2* ( 1 - 0.9788)

= 2*0.0212

= 0.0424

c)

Therefore, p = 0.0424 > $\alpha$ = 0.01

Is is concluded that the null hypothesis is fails to reject.
