For n = 40 and π= 0.6, use the normal distribution to approximate the following probabilities a. X 20 b. X>20 c. Xs 20 d. X <20
For n = 100 and 1=0.4, use the normal distribution to approximate the following probabilities. a. X = 30 b. X>30 c. XS 30 d. X < 30 a. The approximate probability that X = 30 is (Round to four decimal places as needed.)
For n = 40 and 1 = 0.4, use the normal distribution to approximate the following probabilities. a. X=25 b. X> 25 c. X s 25 d. X<25 . a. The approximate probability that X = 25 is (Round to four decimal places as needed.)
For n = 80 and 1 = 0.6, use the normal distribution to approximate the following probabilities. a. X= 50 b. X> 50 c. X 550 d. X<50 a. The approximate probability that X = 50 is 17. (Round to four decimal places as needed.)
0, otherwise a. Show that c-120. b. Find P(X, >1/2) c. Find the joint distribution of-X,-X, and ½-X2 . Draw graphs that illustrate the effect of this transformation on the support.
Look at the image, thank you. For a standard normal distribution, find c if P(z>c) = 0.6906 c=
Assume that X and Y are independent and follow normal distributions with Hx (a) evaluate P(X +Y > 24) (2pt) (b) that P(z < X-Y < 10) = 0.2 (3pt) find r such

4. Let X, Y, and Z be independent random variables, each with the standard normal distribution. Compute the following: (a) P[X + Y> Z +2 (b) Var3x 4Y;
.X, be an id sample from the distribution r >1 (a) Using this distribution, find Eflog(X) 0.
