Find the if the random variable Z is from a standard normal population.

Question

0.6842


0.7152


0.6215


0.5910


0.4869

Answer 1

To find the probability associated with a standard normal random variable Z, you need to look up the value in a standard normal distribution table.

For the values given, the closest one to a standard normal distribution table is 0.4869.

Looking up 0.4869 in a standard normal distribution table, we find that the probability associated with this value is approximately 0.685.

So, the probability for a standard normal random variable Z to be greater than 0.4869 is approximately 0.3151.
