If Y = aX + b then and .Need help with this problem!!!
You are planning to take to a trip to Montreal, Canada during the month of April and you want to bring clothing that is appropriate for the weather. The daily high temperature X in degrees Celsius in Montreal during April has expected value E(X) = 9.7oC with a standard deviation SD(X) = 3.7oC. You want to convert these Celsius temperatures to oF (degrees Fahrenheit). The conversion of X into degrees Fahrenheit Y is Y = (9/5)X + 32.
The expected value in Fahrenheit is 49.46 but how would you calculate the standard deviation into Fahrenheit??? It is not 38.66.
