SKILL BUILDER 7: THE 95% RULE
In Exercises 2.118 to 2.121, use the 95% rule and
the fact that the summary statistics come from a dis-
tribution that is symmetric and bell-shaped to find
an interval that is expected to contain about 95% of
the data values.
2.118 A bell-shaped distribution with mean 200
and standard deviation 25.
2.119 A bell-shaped distribution with mean 10 and
standard deviation 3.
2.120 A bell-shaped distribution with mean 1000
and standard deviation 10.
2.121 A bell-shaped distribution with mean 1500
and standard deviation 300.

Introduction: The top of the graph, which provides a symbolic image of the average, median, and mode for a normal distribution, will possess the same score. Because the cumulative distribution graph of the normal distribution resembles a bell, it is generally referred to simply as the bell curve. When using various statistical methods data and arriving at conclusions, it is beneficial to have a symmetrical distribution. In the given scenario, we need to find the 95% of data distribution for the given normally distributed data. The mean and standard deviation were provided for finding the 95% area of the distributions.
