Z is the standard normal distribution. Find the indicated probability. (Round your answer to four decimal places.) P(−1.62 ≤ Z ≤ 0.11)

Question

You may need to use the appropriate appendix table or technology to answer this question.

Z is the standard normal distribution. Find the indicated probability. (Round your answer to four decimal places.) P(−1.62 ≤ Z ≤ 0.11)

Answer 1

P(-1.62 ≤ Z ≤ 0.11) = P(-1.62 ≤ Z ≤ 0) + P(0 ≤ Z ≤ 0.11)

P(-1.62 ≤ Z ≤ 0) =P(0 ≤ Z ≤ 1.62) = .4474

P(0 ≤ Z ≤ 0.11) = .0438

P(-1.62 ≤ Z ≤ 0.11) = .4474 + .0438 = 0.4912

Remember: The value of Z with a tenth digit from appendix table is on the left most column. However, if the value of Z has a hundredth digit, you have to match it on the top row.
