Find the indicated area under the curve of the standard normal distribution; then convert it to a percentage and fill in the blank.
About ________% of the area is between z = -3.5 and z = 3.5 (or within 3.5 standard deviations of the mean).
Solutions
Expert Solution
P(-3.5 < Z < 3.5) = P(Z < 3.5) - P(Z < -3.5) = 0.9998 - 0.0002 = 0.9996 = 99.96% (ans)
