Find the indicated probability assuming that x is a random variable with a normal distribution with the given mean and standard deviation. (Round your answer to four decimal places.) P(82 ≤ x ≤ 293), μ = 20, σ = 100
Added by Javier P.
Step 1
62 For x = 293: z2 = (293 - 20) / 100 = 273 / 100 = 2.73 Now, we need to find the probability P(0.62 ≤ z ≤ 2.73). We can do this by finding the area under the standard normal curve between these two z-scores. Show more…
