The range is . (b) Find the variance and the standard deviation. Assume the data represent samples, and use the shortcut formula for the unbiased estimator to compute the variance and standard deviation. Round your answers to at least one decimal place. The variance is /The standard deviation is (c) Use the range rule of thumb to estimate the standard deviation. Round your answer to one decimal place. Using the range rule of thumb, ≈s. (d) Compare the estimate to the actual standard deviation. The range rule of thumb ▼(Choose one) a reasonable estimate for the standard deviation for this data.
In order to use the defining formula for variance, we must calculate (x − x)2 for each data value in the data set 14, 18, 22, 26, 33. Use the values in the data set and the mean x = 22.6 to fill out the following table. x 14 18 22 26 33 x 22.6 22.6 22.6 22.6 22.6 x − x 14 − 22.6 = −8.6 18 − 22.6 = __________ 22 − 22.6 = −0.6 26 − 22.6 = _________ 33 − 22.6 = 10.4 (x − x)2 73.96 __________ 0.36 ________ 108.16
