a.

Select the null and the alternative hypotheses for the test.

H0: = 26; HA: 26 H0: 26; HA: > 26 H0: 26; HA: < 26

   

b.

Use Excel's function Z.TEST to calculate the p-value. Assume that the population standard deviation is $5. (Round your answer to 4 decimal places.)

   

  p-value   

   

c.

At = 0.10 what is the conclusion?

   Reject H0; the hourly wage is less than $26. Reject H0; the hourly wage is not less than $26. Do not reject H0; the hourly wage is less than $26. Do not reject H0; the hourly wage is not less than $26.

Explanation / Answer

a) Claim : The average hourly wage is less than $26.

Null and alternative hypothesis is

H0: 26; HA: < 26

b) First enter hourly wages data into excel.

For finding p value use excel command =ZTEST(select values,26,5).

We get p-value = 1 - 0.962802 = 0.0371

c) p value < 0.1 so we reject null hypothesis.

Correct option is

Reject H0; the hourly wage is less than $26.
