Is this statement true or false?"All Normal curves satisfy the "68-95-99.7" rule.

The statement is true.

Here are the steps to explain why:

1. The "68-95-99.7" rule, also known as the empirical rule, is a shorthand used to remember the percentage of values that lie within a certain number of standard deviations from the mean in a normal distribution.

2. Specifically, the rule states that for a normal distribution:

   • Approximately 68% of the data falls within one standard deviation of the mean.
   • Approximately 95% falls within two standard deviations.
   • Approximately 99.7% falls within three standard deviations.

3. This rule applies to all normal distributions, regardless of the mean and standard deviation.

4. Therefore, all Normal curves do satisfy the "68-95-99.7" rule.
