Given that z is a standard normal random variable, what is the probability that z $\geq$ -2.12?
A) 0.4830
B) 0.9830
C) 0.017
D) 0.966

Quizplus · Accepted Answer

The probability that z is greater than or equal to -2.12 is found by looking up the cumulative probability for -2.12 in the standard normal distribution table, which is approximately 0.017. Since we want the probability of z being greater than -2.12, we subtract this from 1, giving us 0.9830.
