g The test statistic of z=2.27 is obtained when testing the claim that p≠0.826. 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 α=0.01, should we reject H0 or should we fail to reject H0?

a. Hypothesis test is two tailed as is two tailed.

b.  p-value =p-value

c.  We failed to reject .

Step-by-step explanation:

Given : Test statistic : z = 2.27

Claim: p ≠ 0.826 i.e. Alternative hypothesis : [ alternative hypothesis takes ≠]

a. Hypothesis test is two tailed as is two tailed.

b. The two-tailed p-value for z=2.27 is 0.0232. [By p-value table]

c. Using a significance level of α=0.01,

p value > α

so we failed to reject . [When p-value >  α we cannot reject null hypothesis.]

idk man good luck man
