Gsuppose that a temperature is represented by the random variable x, whose units are in rankine, with standard deviation 6 rankine. let y be the equivalent random variable with units converted to degrees celsius. what is the variance of y , rounded to one decimal point?
Answers: 3
degrees Rankine is about 
degrees Celsius, so that
is![\mathrm{Var}[Y]=\mathrm{Var}\left[\dfrac59X-\dfrac{5463}{20}\right]=\dfrac{25}{81}\mathrm{Var}[X]=\dfrac{100}9\approx\boxed{11.1}](/tpl/images/0156/5530/c5048.png)
