The P-value is the area under the standard normal distribution curve that is to the left of the test statistic. In this case, the test statistic is z = 0.5, so the P-value is the area under the standard normal distribution curve that is to the left of z = 0.5. This area is equal to 0.6915.

A) 3085 B) 69

A) 3085
B) 69
