b) what z - score on the normal curve has an area of 0.6808 to its graph?\nz =
Answer
Explanation:
Step1: Use z - table
We use the standard normal distribution table (z - table). The z - table gives the cumulative area under the standard normal curve to the left of a given z - score.
Step2: Find the z - score
Looking up the value 0.6808 in the body of the standard normal table, we find the corresponding z - score.
Answer:
0.47
