Q11. Every chi-square distribution is identified by A. Its number of degrees of freedom. B. Its number of parameters. C. Its number of non-parametric characteristics. D. Its number of descriptive statistics parameters. E. Its number of inferential statistics parameters.Q12. The following are all properties of chi-square curves except A. The total area under a ?2-curve equals 1. B. The ?2-curve starts at 0 on a horizontal axis and extends indefinitely to the right approaches but never touches the horizontal axis as it does so. C. The ?2-curve is the same as the t-curve as the number of degrees of freedom decreases. D. The ?2-curve is right skewed E. As the number of degrees of freedom becomes larger, ?2-curve looks increasingly like normal curves.Q13. For a ?2-curve with 12 degrees of freedom, find ?2(0.05). A. ?2(0.05).=25.026 B. ?2(0.05).=23.026 C. ?2(0.05).=21.026 D. ?2(0.05).=23.337 E. ?2(0.05).=25.338Q14. Determine the ?2 value having an area of 0.025 to its left for a ?2 – curve with df=8. A. ?2(0.025,8)left.=2.026 B. ?2(0.025,8)left.=1.026 C. ?2(0.025,8)left.=2.180 D. ?2(0.025,8)left.=2.250 E. ?2(0.025,8)left.=2.258Q15. For a ?2 – curve with df=20, determine the two ?2 values that divide the area under the curve into a middle 0.95 and two outside 0.025 areas. A. (9.951 and 34.170) B. (5.951 and 34.170) C. (9.951 and 43.170) D. (9.591 and 34.170) E. (5.951 and 43.170)
