A. True
B. False

Answer 1

Answer:

The answer is true

Step-by-step explanation:

True

Answer 2

Answer:

A. True

Step-by-step explanation:

The empirical rule in statistics states that:

• 68% of the data will be within 1 standard deviation
• 95% of the data will be within 2 standard deviations
• 99.7% of the data will be within 3 standard deviations

So yes, we can state that 5% or less of the data will be more than 2 standard deviations away from the mean. Of course, statistics is not 100% certain, so this rule is not 100% right all the time. Some exceptions might result, but generally speaking, the results should follow the empirical rule.
