7. wald's test in 1 dimension bookmark this page comparing quantiles 0/1 point (graded) let z∼n(0,1). then z2∼χ21 . the quantile qα(χ21) of the χ21− distibution is the number such that p(z2> qα(χ21))=α. find the quantiles of the χ21 distribution in terms of the quantiles of the normal distribution. that is, write qα(χ21) in terms of qα′(n(0,1)) where α′ is a function of α . (enter q(alpha) for the quantile qα(n(0,1)) of the normal distribution.)

In δabc, m∠acb = 90°, cd ⊥ ab and m∠acd = 45°. find: a find cd, if bc = 3 in

Estimate the time en route from majors airport (area 1) to winnsboro airport (area 2). the wind is from 340° at 12 knots and the true airspeed is 136 knots. magnetic variation is 5° east.

Researchers are conducting experiments to determine the role of alcohol in the development of depression. after the study is complete, they determine that the relative risk of developing depression is 1.55 with a 95 % ci of 1.2 -1.9. each group is then divided into nonsmokers and smokers. the relative risk for the nonsmokers is 1.12 with a 95% ci of 0.87-1.37. the relative risk for the smokers is 1.7 with a 95 % cl of 1.5-1.9. what type of bias may affect this study? a. procedure bias b. recall bias c. selection bias d. confounding e. lead-time bias
