Americans? Is there a difference in the sitting height between the Arctic and Great Plains native Two random samples provided the following results: Arctic n = 8 X1=864.9 S = 488.2 Plain n = 16 X2 = 882.7 S=432.6 5. A 95% interval estimate for the difference between the two population means is: (B) A. -1.654 to 37.254 B. -1.257 to 36.857 C. 1.907 to 37.507 D. -2.1 to 38.212 E. None of the above A. 1.937 B. 1.898 C. 1.822 D. 1.945 E. None of the above 6. The test statistic has a value of: (A) 7. The p-value for this test is closest to: (D) A. > 0.025 & 0.01 & < 0.025 D. > 0.05 & 0.1
