p(-1.20 < Z < 2.03)
Find the following probabilities for a standard normal variable, Z 1) P(Z<-1.27) 2) P(-2.03<Z<3.49) 3) P(Z>1.74) 4)P(Z<0.17) B. Find z if we know that the area to the left of z (under the normal curve) is 0.9265.
If Z is a Standard Normal variable, then P(Z > -1.20) =

P(z -1.02)(Round to four decimal places as needed.) b. Pize 2.03)=[] (Round to four decimal places as needed.) ook c. P(0.68 szs2.03) (Round to four decimal places as needed.) d.P(-2.66 s zs 1.56) = [□ (Round to four decimal places as needed.)
Using Standard Normal Distribution, find the posibilitity 1. P( 0 < Z < 2.16 ) 2. P( -1.87 < Z < 0) 3. P( -1.63 < Z < 2.17) 4. P( 1.72 < Z < 1.98) 5. P( Z > 1.77) 6. P( Z > - 1.02) 7. P (Z < 2.03)
Find the p-values for the following critical values: (Assume two sided hypothesis) 2.03 1.50 1.40 2.26
P(z>0.23 or z<-0.23) = P(-3<z<O) = P(-0.23<z<2.35) = P(z>1.47 or z<-1.47) = P(z<-2 or z>-1) = P(-3<z<3) -
A vertical line is drawn through a normal distribution at z = 1.20. What proportion of the distribution is on the left-hand side of the line? 0.8849 OR 0.1151 ???

Stock Y has a beta of 1.20 and an expected return of 11.4 percent. Stock Z has a beta of .80 and an expected return of 8 percent. If the risk-free rate is 2.5 percent and the market risk premium is 7 percent, are these stocks correctly priced? Stock Y Stock Z
What is z0 if P(z > z0) = 0.12 P(z < z0) = 0.2 P(z > z0) = 0.25 P(z < z0) = 0.3
