At a factory, certain metal components are manufactured on two different machines (A and B). The quality control manager suspects that machine B produces components that are stronger and more durable than those produced by machine A. To test this, he randomly selects twelve components from each machine. The components are put through a wear-testing machine and the amount of wear (in mm) is recorded. Which one of the following statements is the correct formulation of the alternative hypothesis? O a. H₁: Hd <0 O b. H₁: Hd > 0 O c. H₁: VA HB O e. H₁: HA #HB The p-value of this test is equal to 0.064. Based on the p-value, indicate the strength of the evidence in favour of the alternative hypothesis. O a. Very strong evidence O b. Strong evidence c. Moderate evidence O d. Weak/no evidence
