A Chemist Is Interested in Comparing Four Different Catalysts by Measuring

question 27

Multiple Choice

A chemist is interested in comparing four different catalysts by measuring reaction times.Each catalyst is tested five times,with each experiment randomly assigned one of the four catalysts.

• A)H0: μcat ≠ μtest vs.the alternative that catalyst and test mean times are equal
• B)H0: μ1 ≠ μ2 ≠ μ3 ≠ μ4 ≠ μ5 vs.the alternative that all the test mean times are equal
• C)H0: μ1 = μ2 = μ3 = μ4 vs.the alternative that not all the catalyst mean times are equal
• D)H0: μ1 ≠ μ2 ≠ μ3 ≠ μ4 vs.the alternative that all the catalyst mean times are equal
• E)H0: μ1 = μ2 = μ3 = μ4 = μ5 vs.the alternative that not all the test mean times are equal
