For a standard normal distribution, find:

P(z < -0.64)
Express the probability as a decimal rounded to 4 decimal places.

Expert Solution

Here' the answer to the question. Please let me know in case you've doubts.

Lets take a look at the Z-table.

Lets see what is the cumulative value at -0.64.

It is can be found here ( see how i have highlighted -0.64 to get the probability value corresponding to this Z value:

It is 0.2611

Answer : P(Z< -.64) = 0.2611
