Let z be a random variable with a standard normal distribution. Find the indicated probability. (Round your answer to four decimal places.) P(−1.22 ≤ z ≤ 2.61) =
Shade the corresponding area under the standard normal curve.
Solution:
Given that,
P(−1.22 ≤ z ≤ 2.61)
P(z ≤ 2.61) - P( z ≤ −1.22)
Using standard normal table,
0.9955 - 0.1112
= 0.8843
Probability = 0.8843
