Given the same data set as described in the problem above, approximat data falls between 5.0 and 12.5? a. 16% b. 34% C. 68% d. 81.5% e. 99.7%

Explanation / Answer

Ans:

12)

According to Empirical rule,approximatelyn 68% of the data falls within one standard deviation fof the mean.

So,option d is correct.(68%)

13)mean=10

standard deviation=2.5

5 and 15 are two standard deviation above and below the mean.

so,approximately 95% of the data falls within 5 and 15.

14)5 is two standard deviation below the mean and 12.5 is one standard deviation above the mean,so

P(-2<z<1)=P(z<1)-P(z<-2)=0.8413-0.0228=0.8185

Approximately 81.5%.
