Question 1 (20 points) Listen Madam Hooch is testing out a new model of broomstick called the Starlight 900 for the players of her Quidditch team. She knows that the mean number of blocks for a Keeper is 52. She counts the number of blocks for 9 Keepers on the new broom and finds a mean of 56 with a variance of 136.80. What is the estimated standard error for the Keepers' blocks on the new broom model? (Round your answer to two decimal places.) Your Answer: Answer Question 2 (20 points) Listen 4 Dr. Alito is testing the effect of a particular drug on how fast rats will complete a maze. He knows the average time it takes a rat to finish this maze is 12 seconds. He gives 7 rats the drug and tests them in the maze and finds that their mean time is 84 seconds with a SS 1,935. What is the calculated t-value for this sample? Round your answer to two decimal places. Do not include + signs if your answer is positive; include a- if your answer is negative. t= (M-HM) SD 8M where SM= n SD2 SS = n-1 SD = SS n-1 Your Answer: Question 1 (20 points) Listen Madam Hooch is testing out a new model of broomstick called the Starlight 900 for the players of her Quidditch team.
