In 2013 Boston Red Sox were the World Series champions. During the regular season, they won 98 of 162 games. You want to estimate the overall population proportion of games won by the Boston Red Sox for all years using 95% confidence interval. Answer parts (a) through (d). 2(a). What is the sample proportion and what is the critical value? Round your answers to 3 decimal places. = =

10. In 2013 Boston Red Sox were the World Series champions. During the regular season, they won 98 of 162 games. You want to estimate the overall population proportion of games won by the Boston Red Sox for all years using 95% confidence interval. Answer parts (a) through (c). 10(a). Do not calculate! Use appropriate TI-calculator option to construct 95% confidence interval. x % < p < y % (find x and y and Round your answers to integers.) 10(b). What can you tell about the confidence interval that would be calculated? Group of answer choices - They could lose more than half of games or win more than half of games. - They always win more games than they lose. - They normally lose more than they win. - They normally win more than they lose. 10(c). Actually, the confidence interval in 10(b) is not valid. What was wrong here?

In the 1996 regular baseball season, the World Series Champion New York Yankees played 80 games at home and 82 games away. They won 49 of their home games and 43 of the games played away. We can consider these games as samples from potentially large populations of games played at home and away. How much advantage does the Yankee home field provide? a. Find the proportion of wins for the home games. Do the same for the away games. b. Find the standard error needed to compute a confidence interval for the difference in the proportions. c. Compute a 90% confidence interval for the difference between the probability that the Yankees win at home and the probability that they win when on the road. Are you convinced that the 1996 Yankees were more likely to win at home?
