À baseball analyst would like to study various team statistics for a recent season to determine which variables might be useful in predicting the number of wins achieved by teams during the season. He begins by using a team's earned run average (ERA), a measure of pitching performance, to predict the number of wins. He collects the team ERA and team wins for each of the 30 teams in a two-league organization, with the accompanying results. Complete parts (a) through (1) below. Но H : (Type integers or decimals. Do not round.) Determine the test statistic. tSTAT = (Round to two decimal places as needed.) Determine the p-value. The p-value is. (Round to three decimal places as needed.) State the conclusion. Ho. There evidence of a linear relationship between the number of wins and the ERA. f. Construct a 95% confidence interval of the mean number of wins expected for teams with an ERA of 4.00. OSHYX = 4.00 O (Round to one decimal place as needed.) g. Construct a 95% confidence interval estimate of the population slope.
