(a) suppose z is a standard normal random variable. compute the following probabilities using excel template 3 (available in canvas).

a. p(1.23 z 2.58)

b. p(1.83 z 1.96)

c. p(z 1.32) d. p(z 2.52)

e. p(z 1.63)

f. p(z 1.38)

g. p(2.37 z 1.54)

(b) suppose z is a standard normal random variable. find the z-value given probabilities:

z-value with .10 in the upper tail

z-value with .05 in the lower tail

c. z-value with .05 in the upper tail

(A). Suppose z is a standard normal random variable. Compute the following probabilities: 1. P(1.23z2.58) = z-value with 0.10 in the uppertail 2. P(1.83z1.96) 3. P(z1.32) 4. P(z2.52) 5. P(z1.63) 6. P(z1.38) 7. P(2.37z1.54) (B). Suppose z is a standard normal random variable. Find the z-value given probabilities: 1. 2 -value with 10 in upper tail 2. z-value with 05 in lower tail 3. z-value with 05 in upper tail
