Does the pressure of playing in the final round cause scores to go up? Or does the increased player concentration cause scores to come down? a. Use a - -10 to test for a statistically significantly difference between the population means for first- and final-round scores. What is the p-value? p-value is 2402 (to 4 decimals) What is your conclusion? There is no v @ significant difference between the mean scores for the first and final rounds. b. What is the point estimate of the difference between the two population means? 1.4 (to 2 decimals) For which round is the population mean score lower? First round v c. What is the margin of error for a 90% confidence interval estimate for the difference between the population means? 3.3 (to 2 decimals) Could this confidence interval have been used to test the hypothesis in part (a)? Yes v Explain. Use the point of the difference between the two population means and add and subtract this margin of error. If zero |is v in the interval the difference is not statistically significant. If zero |is not v @ in the interval the difference is statistically significant.
