Explanation / Answer

Ans:

a)Dollars

b)

1)Quantitative

2)1000 and 2200 are 2 standard deviations(600) away from the mean i.e. 1600

So,based on empirical rule,95% of the data lies within 2 standard deviations of the mean.

Correct option is approximately 95%

3)700 and 2500 are 3 standard deviations(900) away from the mean i.e. 1600

So,based on empirican rule,99.7% of the data lies within 3 standard deviations of the mean.

Correct option is approximately 99.7%

4)1300 and 2900 are 1 standard deviations(300) away from the mean i.e. 1600

So,based on empirical rule, 68% of the data lies within 1 standard deviations of the mean.

Correct option is approximately 68%

5)an unknown number

(atleast 75% lies between 1000 and 2200 not 1600 and 2200.
