Let z be a standard normal random variable with mean 𝜇 = 0 and standard deviation 𝜎 = 1. Find the value c that satisfies the inequality. (Round your answer to two decimal places.) P(−c < z < c) = 0.96 c=
Added by Jean P.
Step 1
This means that if we want the probability of z being between -c and c to be 0.96, then we want the tails (the areas under the curve to the left of -c and to the right of c) to make up the remaining 0.04 of the probability. Since the distribution is symmetric, Show more…
