In what follows use any of the following tests/procedures:Regression, confidence intervals, one-sided t-test, or two-sidedt-test. All the procedures should be done with 5% P-value or 95%confidence interval. Open Brain data. Claim: Male and femalesubjects have different total (brain) surface areas. 9. Whattest/procedure did you perform? a. One-sided t-test b. Regressionc. Two-sided t-test d. ​​Confidence interval 10. What is theP-value/margin of error? a. 0.450365624 b. 1.10877E-11 c.0.435460528 d. 0.900731248 e. ​​None of these 11. Statisticalinterpretation a. The 95% confidence interval does not contain theaverages. b. Since P-value is too large we cannot conclude that thetwo variables have different averages. c. Since P-value is toolarge we cannot claim that there is connection between twovariables. d. Since P-value is small we can claim that there isconnection between two variables. e. None of these 12. Conclusiona. Yes, I am confident that the averages are different. b. No, Icannot claim that the average are different.
