This is driving me crazy...
"A Machine fills a 3 pound coffee can with a measured amount of coffee. The Weight has a normal distribution with a mean of 3.1 pounds. The standard deviation is 2.0 OUNCES. What is the probability that a can picked at random will contain less than 3 pounds.
Ok so first I converted the SD to pounds (2.0 Ounces/ 16 Ounces = 0.125 Pounds)
I calculated the Z score, $\frac{2.9 - 3.1}{0.125} = -1.6$
I looked up the standard area table -> 0.0548
Wouldn't this be 5.48% or am I messing something up? Or this isn't probability?
