About .91\n\nJava applet for it here: http://davidmlane.com/hyperstat/z_table.html\n\nFine.  Without an applet, go to any Z-table, such as here: http://lilt.ilstu.edu/dasacke/eco138/ZTable.htm\n\nP(Z < 1.7) - P(Z < -1.7)  (Look up both of these in the table).\n= .9554 - .0446 = .9108

-11a + 7 < -12a + 18 \n a + 7 < 18            .( Added 12a to both sides)\n a < 11                .(Subtracted 7 from both sides)\n\na < 11 (FINAL answer- a is less than 11)

Use a Normal table to find that the value of z so that Probability that Z < z = .90 is z = 1.2816.\n\nNow set z = 1.2816 = (x-100)/15, and solve for x:\n\nx = 1.2816*15 + 100 = 119.224

-12.4 = -19.1 + n/-7.9\nThis can also be written as:\n-19.1 + n/-7.9 = -12.4\nn/-7.9 = 19.1 - 12.4\nn/-7.9 = 6.7\nn = (6.7)(-7.9)\nn = -52.93

(z^4)^2 - 14z^4 +16 =0\nQuadratic factoring:\nz^4 = (14+sqrt(196-64))/2 = 7+sqrt(33) =\n12.7446 so z = 1.89 or -1.89\nOR\nz^4 = 7-sqrt(33)= 1.2554\nso z= 1.059 or -1.059

z/0.23-0.11=0.17\n=>z /0.23=0.17+0.11=0.28\n=>z=0.28X0.23 =0.0644=0.1 (rounded to the nearest tenth)\nTherefore,(D) is correct

Let the numbers be x, y and z.\nThen xyz = x + y +z\n.Also the numbers must be small, as this is not possible for large numbers.\nThe other set is -1, -2, -3 and -1,0,1 and 2,0,-2 and \n-n,0,n

I just taught this to my statistics class today.\nZ_alpha/2 is a number such that\nP(0<z<z_alpha/2) = alpha/2\nIf alpha = .95, then alpha/2 = .95/2 = .475\nz_.475 = 1.96\nIf alpha = .90, then alpha/2 = .90/2 = .45\nz_.45 = 1.645\nThe numbers 1.96 and 1.645 come from the body table.
