Find the fraction of standard normal distribution observations that satisfy each of the following statements using Table A. Draw a standard normal curve in each scenario and shade the area under the curve that corresponds to the answer to the question.

The table of areas beneath the standard normal curve is called the below standard normal probabilities table. The area under the curve to the left of each number $z$is the table entry.

The area to the left of $z=-2.46$is $0.0069$.

Find the fraction of standard normal distribution observations that satisfy each of the following statements using Table A. Draw a standard normal curve in each scenario and shade the area under the curve that corresponds to the answer to the question.

The area to the left of $z=2.46$is $0.991$. Thus, the area to the right of $z=2.46$is $1-0.9931=0.0069$.

Find the fraction of standard normal distribution observations that satisfy each of the following statements using Table A. Draw a standard normal curve in each scenario and shade the area under the curve that corresponds to the answer to the question.

From the Standard Normal probabilities table, the area to the left of $-=0,89$is $0.8133$and the area to the left of $z=2.46$is $0.9931$. The area between $z=2.46$and $z=0.89$is the area to the left of $2.46$minus the area to the left of $0.89$.

Therefore, the area between $z=0.89\&z=2.46$is $0.9931-0.8133=0.1798$.

Find the fraction of standard normal distribution observations that satisfy each of the following statements using Table A. Draw a standard normal curve in each scenario and shade the area under the curve that corresponds to the answer to the question.

From the Standard Normal probabilities table, the area to the left of $z=-1.27$is $0.1020$and the area to the left of $z=-2.95$is $0.0016$. The area between $z=-2.95$and $z=-1.27$is the area to the left of $-1.27$minus the area to the left of $-2.95$.

Therefore, the area between $z=-2.95\&z=-1.27$is $0.1020-0.0016=0.1004$.
