Statistics!
Anybody on this board good with Stats? I'm having a bit of difficulty answering these questions about a problem on my homework. If anybody is willing to help that would be awesome!

If you want help, maybe you should post the actual problem.

I figured I'd at least ask first.
Anyways, problem... During September, the average temperature of Laurel Lake is 64.2 and the standard deviation is 3.2. Assume the variable is normally distributed. For a randomly selected day, find the probability that the temperature will be: a. Below 67 b. Between 65 and 68 |

ew. statistics.
It isn't too bad. I can help you with part.....but I don't have any tables so the rest is up to you. You gotta find your Z, right? z=(67-64.2)/ 3.2 and so on..... μ = 64.2 σ = 3.2 |
