Question

Test whether μ1 ≠ μ2 at the α = 01 level of significance for the given sample data.

                Population 1         Population 2    

n              17                            17

x             10.2                        12.7

s              2.2                           3.2

Test whether μ1 ≠ μ2 at the α = 0.01 level of significance for the given sample data. Determine the null and alternative hypothesis for this test.

H0 :μ1 ≠ μ2    H1 :μ1 > μ2

H0 :μ1 = μ2    H1 :μ1 > μ2

H0 :μ1 ≠ μ2    H1 :μ1 = μ2

H0 :μ1 = μ2   H1 :μ1 ≠ μ2

Determine the P-value for this hypothesis test. 

P =_____________________  (Round to three decimal places as needed.)

Should the null hypothesis be rejected?

  1. Reject H0 , there is not sufficient evidence to conclude that the two populations have different
  2. Do not reject H0 , there is not sufficient evidence to conclude that the two populations have different
  3. Do not reject H0 , there is sufficient evidence to conclude that the two populations have different
  4. Reject H0 , there is sufficient evidence to conclude that the two populations have different
