Question
In a standard normal distribution, the probability that Z is greater than zero isQuestion 4Select one:a.0.0500b.0.2546c.0.5d.0.5123
Solution
The standard normal distribution is symmetric around zero. This means that the probability of a randomly selected value being greater than zero is the same as it being less than zero. Since the total probability under the curve of the distribution is 1, the probability that Z is greater than zero is 0.5. So, the correct answer is c. 0.5.
