Stats question

[alexjohnson16]

Engineers must consider the breadths of male heads when designing motorcycle helmets. Suppose men have head breadths that are normally distributed with a mean of 6.0 inches and a standard deviation of 1.0 inch.

If one male is randomly selected, find the probability that his head breadth is less than 6.2 inches. Round to the nearest thousandth.

Is this normalcdf(6.2,999999,6,1)?

You're asking someone else how to get your calculator to do your homework for you?

...do I get paid, at least?

I'm asking if that is the right equation to figure the problem out.

I'm not sure if the 999999 should be negative or positive.

why do you need a calculator for that?
anyways, why do you even need the 99999?

but if he offers money, it's cheating and someone from ATOT will tell on his dean.

I tried to erase any trace of stats from my mind after I finished Stats I + II

I would highly recommend that you draw a picture for any problem dealing with a normal distribution. In this case, if you draw a picture of the situation, you should be able to figure out whether the 999999 should be + or -.
