Question

During the current NFL season, Matthew has correctly predicted the winning team in 90 of the last 160 games. His friend Ryan has predicted the winning team in 104 of the last 60 games. a. [2 points] If we consider the results of each NFL game to be independent, construct a 96% confidence interval for the difference in the proportion of games that Ryan and Matthew pick correctly. Round to three decimal places. b. [1 point] Based on your confidence interval, can we conclude that Ryan picks NFL games better than Matthew? Explain why or why not, using your knowledge of confidence intervals.

Answer 1

Matthew better than ryan

Step-by-step explanation:

so if Matthew have 90/106=0.84

0.84+212 since A 2 point every single game so 212.84

Ryan 104/60=1.73

60 game × 2 120

120+1.73=121.73
