Suppose we have the following information about two samples: Sample 1 Sample 2 n1 = 35 n2 = 45 X1 = 82 X2 = 79 S1 = 15 S1 = 18 If we have a level of significance = 0.10, and a upper one-tailed test, what is the critical value? O a. 1.667 O b. 78 O c. 1.645 O d. 1.293 O e. 77For Questions 2 through 9, you will use the information below: Suppose we have a blackjack player who is looking to see if her new card counting technique is more protable than her old one. To see if the new one is better, she plays blackjack for 60 days using her old technique and 60 days using her new technique, collecting her prot data from each sample. Because she's been playing blackjack for so long, she has a pretty good idea what the population standard deviation for prot looks like: a] = S 22 (new card counting technique), and 02: $ 3] (old card counting technique). Sample 1 (new) Sample 2 (old) Calculate the point estimate for the difference in prot from her new technique compared to her old technique.
