A data set consisting of 525 standardized test scores is known to have a bell-shaped (normal) distribution with a mean of 65 and a standard deviation of 5.

Use the Empirical Rule to address the following questions.

Hint: sketch the distribution to help visualize the problem.

Approximately 99,7% of the test scores lie between---------- and---------

What approximate percentage of the test scores lie between the scores 55 and 75?---------%

What approximate percentage of the test scores lie between the scores 60 and 70?---------%
