8. In 2008, 25% of players in Major League Baseball (MLB) were left handed. Suppose you wish to test the hypothesis that the proportion of left handed players in the MLB is the same (0.25) versus the hypothesis that the proportion is now greater than 0.25. You analyze a the roster of a randomly chosen team and conduct a hypothesis test. The 30 players are listed below with their dominant hand "R" for right handed and "L" for left handed. LRRRLL RLLRRL RRLRRR RRRLRR RRLLLR Complete the following parts in your notebook and upload an image of your answer to be graded. You may use your inference guide to help you. (a) Check the conditions for the hypothesis test. Are the conditions met? Why/why not? (b) Whether or not the conditions are met in part a, conduct the hypothesis test at a 5% significance level. Be sure to show clearly the four steps: State, Plan, Show, and Conclude. Remember, you should use correct vocabulary and notation. (c) Suppose a friend reads your work for this assignment and says "at least 25% of Americans are left handed". Would you agree with this statement? Why/why not? 8.
