Below are the range and standard deviation for a set of data. Use the range rule of thumb and compare it to the standard deviati

Liula [17]

Solution: We are given:

$Range =2.76$

$Standard-deviation=0.807$

Now let's find the estimated value of standard deviation using the range rule of thumb. According to range rule of thumb, the estimate of standard deviation is:

$S\approx \frac{2.76}{4}= 0.690$

Therefore the estimated standard deviation is 0.690

is this an acceptable approximation?

Answer: c. Yes, because the error of the range rule of thumb's approximation is less than 15%.

Explanation:

The difference between estimated standard deviation and actual standard deviation is:

0.807 - 0.690 = 0.117

Now let's find the percentage of error

$\frac{0.117}{0.807} \times 100= 14.50\%$ .

Therefore, the error of the range rule of thumb's approximation is less than 15%.
