QUESTION 3 Bob believes a box of numbered tickets has an average of 40. Sue believes the average is bigger than that. They draw 400 tickets from the box. The tickets they draw have an average of 48 with a standard deviation of about 35. Sue says, "See? What we drew averaged to 48, way over 40. I think the average of the box is more than 40." Bob says, "That is just the luck of the draw. Of course sometimes what we draw will average over 40, and sometimes what we draw will average under 40. After all, the standard deviation of our draw is 35." State the Null hypothesis and Alternative Hypothesis. ⒸH=40 H:μ>40 Ⓒ11μ>40 H:μ=40 ⒸH₂X=40 H:x>40 ⒸHμ>40 H:p=40 QUESTION 4 Continued.
