Given: Claim: μ1=μ2 σ1=3.4, σ2=1.7 x¯1=15 , x¯2=17 n1=27 , n2=30The alternative hypothesis is the contradictory statement of null hypothesis. Here the null hypothesis is the claim . Hence the alternative hypothesis is H1:μ1≠μ2Standardized test statistic is z=x¯1-x¯2σ12n1+σ22n2=15-173.4227+1.7230≅-2.76The test is two-tailed. Use the Excel formula "=2*NORM.S.DIST(-2.76,TRUE)" to obtain the P-value. P-value≅0.006If the p-value is less than the level of significance, we can reject the null hypothesis. As the p-value 0.006 is less than the level of significance 0.01, we can reject the null hypothesis. Hence, there is enough evidence to reject the claim as the null hypothesis is the claim. The correct option is: Reject H0. There is enough evidence at a 1% level of significance to reject the claim.
