Using either Table A or your calculator or software, find the proportion of observations from a standard Normal distribution that satisfies each of the following statements. (Round your answers to four decimal places.)
(a) Z > 2.08
(b) Z < 2.08
(c) Z > ?0.68
(d) ?0.68 < Z < 2.08
Finding Probabilities Under Normal Curve:
Standard normal curve is a bell-shaped curve that gives probabilities (proportions) random variables assumes in a continuous distribution. The random variables are standardized into z scores that gives number of standard deviations they take below or above the mean.
Answer and Explanation:
On a z table, locate 2.0 on the left most column and move along the row up to column with 0.08 and get the...

In this lesson, we will put the normal distribution to work by solving a few practice problems that help us to really master all that the distribution, as well as Z-Scores, have to offer. Review the concepts with a short quiz at the end.
