Given that z is a standard normal random variable, what is the value ofz if the area to the right of z is 0.1112? a. 0.3888 b. 2.22 c. 3.22 d. 1.22 28. The expected value of a random variable is the a. 29· value of the random variable that occurs most frequently value of the random variable that should be observed on the next repeat of the experiment square root of the variance b. c. d. None of the answers is correctExplanation / Answer
Q 25) Answer : Option d) a continuous random variable
Q 26 Data not given
Q 27) Answer : Option d) the trials are dependent
Q 28) Answer : The area to the right of Z is 0.1112, Therefore the area from 0 to Z is = 0.5-0.1112 = 0.3888
The corresponding value of Z is = 1.22
Answer: Option d) 1.22
Q 29) Answer: Option d) None of the answer is correct
