Suppose Z is a standard normal random variable. (See problem.) If P(-z<z<z) 0.796, find Question 1 Find P(-2.46 <Z<-0.98) Question 2
(1 point) Find the value of the standard normal random variable z, called Zo such that: (a) P(Z <zo) = 0.8319 20 (b) PC-Zo <z<zo) = 0.5508 20 = (c) P(-20 <2<zo) = 0.748 zo = (d) P(z > Zo) = 0.2823 20 = (e) P(-20 <z<0) = 0.0283 Zo = (1) P(-1.5 <2<zo) = 0.7108 zo Note: You can earn partial credit on this problem.
Find a value of a standard normal random variable Z (call it z0) such that (a) P(Z ?20) .30 (b) P(Z> z)16 (c) P(-20< Z<20).90
ULULUI Let Z be a standard normal random variable. What is P(-2.22 <Z<0.25)? 0.2212 0.3488 0.5855 O 0.6902
2. Find the value of c that satisfies each of the following probabilities for a standard normal random variable 2: (a) p(z <c) = 0.975 (b) p(-c<z<c) = 0.95
IS Find the following probability for the standard normal random variable z. a. P(z<-1.02) b. P(z <2.03) c. P(0.68 szs2.03) d. P(-2.66szs1.56) a. 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.)
please explain these throughly!!! Thank you so much! Let Z be a standard normal random variable. Use the calculator provided, or this table, to determine the value of c. P(0.86 <2<c)=0.1737 Carry your intermediate computations to at least four decimal places. Round your answer to two decimal places. Tx 5 ?
