In comparing the average protein content µ1 and µ2 of two brands of dog food, a consumer testing service finds that fifty 5-pund packages of brand A dog food had an average protein content x̅1=11 ounces per package and a s.d of s1 = 1 ounce, while sixty-5 pound packages of brand B dog food has an average protein content x̅2=9ounces per package and a s.d of s2 = 0.5 ounce. A difference of 0.5 ounces is considered to be not sufficiently important to report as a consumer issue. Therefore, a decision was made to test the hypothesis. Ho : H1 - H2 = 0.5 versus H, : µ1 - Hz > 0,5. use the observed data to test these hypothesisat 0.01 level of significance.

Question

In comparing the average protein content µ₁ and µ₂ of two brands of dog food, a consumer testing service finds that fifty 5-pund packages of brand A dog food had an average protein content x̅₁=11 ounces per package and a s.d of s₁ = 1 ounce, while sixty-5 pound packages of brand B dog food has an average protein content x̅₂=9ounces per package and a s.d of s₂ = 0.5 ounce. A difference of 0.5 ounces is considered to be not sufficiently important to report as a consumer issue. Therefore, a decision was made to test the hypothesis.

Ho : H1 - H2 = 0.5 versus H, : µ1 - Hz > 0,5. use the observed data to test these hypothesis
at 0.01 level of significance.
