The increases (in cents) in cigarette taxes for 17 states in a 6-month period are 60, 20, 40, 40, 45, 12, 34, 51, 30, 70, 42, 31, 69, 32, 8, 18, 50 Find the range, variance, and standard deviation for the data. Use the range rule of thumb to estimate the standard deviation. Compare the estimate to the actual standard deviation.

The increases (in cents) in cigarette taxes for 17 states in a 6 -month period are $60,20,40,40,45,12,34,51,30,70,42,31,69,32,8,18,50$ Find the range, variance, and standard deviation for the data. Use the range rule of thumb to estimate the standard deviation. Compare the estimate to the actual standard deviation.
Data Description
Measures of Variation
State Cigarette Taxes The average state cigarette tax per pack (in dollars) from 2001 through 2007 is approximated by the function $$T(t)=0.43 t^{0.43} \quad(1 \leq t \leq 7)$$ where $t$ is measured in years, with $t=1$ corresponding to $2001 .$ a. Show that the average state cigarette tax per pack was increasing throughout the period in question. b. What can you say about the rate at which the average state cigarette tax per pack was increasing over the period in question?
