Statistics Question

[ekassin]

Kiwi Beer is sold in 950ml cans. The mean volume is 945ml and the standard deviation is 15ml. Assuming a normal distribution what is the probability that more than 945ml will be placed in the can.

My first step was to use the equation X-U/ Standard deviation. Using this I came up with 950-945/15 = .33

What is the next step and why.

Thank You

what is the probability that more than 945ml will be placed in the can.

Is this the correct question, if so, the size of the can is a red herring. Instead, you get z = (945 - 945) / 15 = 0.00

Either way, whether z = 0 or 0.33, you then want to find P(Z > z), for which you need to look up a table of normal probabilities (or use MS-Excel or a fancy graphing calculator)
