Using the Empirical Rule, it is found that:
- a) Approximately 99.7% of the amounts are between $35.26 and $51.88.
- b) Approximately 95% of the amounts are between $38.03 and $49.11.
- c) Approximately 68% of the amounts fall between $40.73 and $46.27.
------------
The Empirical Rule states that, in a <em>bell-shaped </em>distribution:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
-----------
Item a:
Within <em>3 standard deviations of the mean</em>, thus, approximately 99.7%.
-----------
Item b:
Within 2<em> standard deviations of the mean</em>, thus, approximately 95%.
-----------
Item c:
- 68% is within 1 standard deviation of the mean, so:
Approximately 68% of the amounts fall between $40.73 and $46.27.

Answer:
The statement is True!
Step-by-step explanation:
Clare paid full price for an item.
Let Price of the item = x
Han bought the same item for 80% of the full price.
Han bought it for 0.8x
Clare said, I cants believe I paid 125% of what you paid, Han!
The above statement is True if;
125% of 0.8x = x
1.25 * 0.8x = x
x =x
The statement is True!
