Example Questions

Example Question #7 : Mean, Standard Deviation, And Normal Distribution

In a normal distribution, what percentage is covered within one standard deviation?

Possible Answers:

99.7%

34%

95%

50%

68%

Correct answer:

68%

Explanation:

By drawing a bell curve, the middle line is 50%. One standard deviation left and right of the middle line is 34% each. That means one standard deviation within is 68%.

Example Question #8 : Mean, Standard Deviation, And Normal Distribution

If the mean is $\small 0$ $\displaystyle \small 0$ and the standard deviation is $\small 3.4$ $\displaystyle \small 3.4$, which of the following is NOT within two standard deviations?

Possible Answers:

$\small \small -6.81$ $\displaystyle \small \small -6.81$

$\small -6.79$ $\displaystyle \small -6.79$

$\small -6.8$ $\displaystyle \small -6.8$

$\small 6.79$ $\displaystyle \small 6.79$

$\small 6.80$ $\displaystyle \small 6.80$

Correct answer:

$\small \small -6.81$ $\displaystyle \small \small -6.81$

Explanation:

Two standard deviations means to double the standard deviation value.

$2\cdot 3.4 =6.8$ $\displaystyle 2\cdot 3.4 =6.8$

This means the range is $\small -6.8$ $\displaystyle \small -6.8$ to $\small 6.8$ $\displaystyle \small 6.8$.

$(0-6.8, 0+6.8)\rightarrow (-6.8,6.8)$ $\displaystyle (0-6.8, 0+6.8)\rightarrow (-6.8,6.8)$

Only $\small -6.81$ $\displaystyle \small -6.81$ is not in the range.

Example Question #9 : Mean, Standard Deviation, And Normal Distribution

Ibram was paid $5000 for editing a 2200-page encyclopedia. What was his rate earned per page?

Possible Answers:

$0.44

$2.27

$1.27

$0.56

Correct answer:

$2.27

Explanation:

This question is really just asking for the average dollar per page. This could be easily calculated:

$\frac{5000}{2200}=2.27$ $\displaystyle \frac{5000}{2200}=2.27$

However, you might also think of this as a rate problem:

D=RT

Using the information from the question, we can see that D=5000 and T=2200.

This comes out to what we solved above:

$R=\frac{D}{T}=\frac{5000}{2200}=2.27$ $\displaystyle R=\frac{D}{T}=\frac{5000}{2200}=2.27$

Example Question #5 : Mean, Standard Deviation, And Normal Distribution

Standard Deviation can be calculated from what statistical term?

Possible Answers:

Quartile

Mode

Range

Median

Variance

Correct answer:

Variance

Explanation:

Another way to calculate standard deviation is the square root of variance.

Variance is,

$\small {\frac{\Sigma (x-\bar{x})^2}{n-1}}$ $\displaystyle \small {\frac{\Sigma (x-\bar{x})^2}{n-1}}$.

Taking the square root of this is how standard deviation can be calculated.

$\sigma=\sqrt{\small {\frac{\Sigma (x-\bar{x})^2}{n-1}}}$ $\displaystyle \sigma=\sqrt{\small {\frac{\Sigma (x-\bar{x})^2}{n-1}}}$
