Web14 aug. 2016 · With those three triangles we get the following equations. { z 2 = 25 + x 2 y 2 = 16 + x 2 81 = z 2 + y 2. Substituting the first two into the third, you can solve for x and get x = 20 = 2 5. Then you can substitute this value of x into the first two equations to solve for y and z. I get that y = 36 = 6 and that z = 45 = 3 5. WebTranscript. If we want to be 95% confident, we need to build a confidence interval that extends about 2 standard errors above and below our estimate. More precisely, it's actually 1.96 standard errors. This is called a critical value (z*). We can calculate a critical value z* for any given confidence level using normal distribution calculations.

If n ll m, find the value of x and the value of z. A. x=9, z=2

Web26 mrt. 2016 · Answer: 15.6. The question gives you a z- score and asks for its corresponding x- value. The z- formula contains both x and z, so as long as you know … WebLet x represent the data value, mu represent the mean, sigma represent the standard deviation, and z represent the z-score. Since the z-score is the number of standard deviations above the mean, z = (x - mu)/sigma. Solving for the data value, x, gives the formula x = z*sigma + mu. chirayu forex
