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)
