The answer is c...............

There is a 99% chance that her true score is between: 6.3 - 33.7

How to make use of the empirical rule in statistics?

At 99% probability under the empirical rule, it will be 2.576 standard deviations from the mean.

Thus, possible score intervals are;

20 ± 2.576(20)

⇒ (20 - 2.576*20) or (20 + 2.576*20)

⇒ 7.061 or 32.939

This falls within the interval in option A.

The complete question is;

Jane obtained a score of 20 on the financial risk-taking scale. There is a 99% chance that her true score is between: a. 6.3 - 33.7 b. 14.0 - 26.0 c. 11.1 - 23.1 d. 8.2 - 31.8. Possible standard of deviation = 5.0229
