For A Standard Normal Distribution, Find The Approximate Value Of P (Z Less-Than-Or-Equal-To 0.42). Use The Portion Of The Standard Normal Table Below To Help Answer The Question. Z Probability 0.00 0.5000 0.22 0.5871 0.32 0.6255 0.42 0.6628 0.44 0.6700 0.64 0.7389 0.84 0.7995 1.00 0.8413 16% 34% 66% 84%. Therefore, the correct answer is option c. The probability p (z ≤ 0.42) in a standard normal distribution is approximately 66%.

The probability p (z ≤ 0.42) in a standard normal distribution is approximately 66%. Table shows the probability (p) that a standard normal variate will have a value less than or equal to z (or the shaded area in the diagram to the right). Therefore, the correct answer is option c.
