# Math Help - standard deviation and mean

1. ## standard deviation and mean

If the temperature in degrees fahrenheit at a certain location is normally distributed with a mean at 68 degrees and a standard deviation of 4 degrees, what is the distribtion of the temperature in degrees Celsius at the same location?

2. Don't you just convert the measurements from Fahrenheit to Celsius or is there something I'm missing?

You're expected to know that if X ~ Normal $(\mu, \sigma^2)$ and $Y = aX + b$ then Y ~ Normal $(a \mu + b, a^2 \sigma^2)$.
