B) 95%
C) 68%
D) 99.7%

Answer 1

The percent of data values in a bell-shaped distribution that is within one standard deviation from the mean is 68%.

Step-by-step explanation:

The percent of data values in a bell-shaped distribution that is within one standard deviation from the mean is 68%.

This is known as the Empirical Rule, which applies to bell-shaped and symmetric distributions.

It is important to note that this rule applies specifically to bell-shaped and symmetric distributions, such as the normal or Gaussian probability distribution.
