WebThe mean is changed both by the multiplication of a constant (there are 1.8 Celsius degrees per Fahrenheit degree) and the addition of a constant (we add 32 to account for the fact that water freezes at 0 C and 32 F). So the mean in terms of degrees F will be: \[\bar{F} = 1.8 \bar{C} + 32 = 1.8(41/6)+32=44.3\]
