Asked by Isabella

The weight of a product is normally distributed with a mean of 4 ounces and a variance of .25 "sq ounces." The company wants to classify the unit as a scrap in a maximum of 1% of the units if the weight is below a desired value. Determine the desired weight such that no more than 1% of the units are below it.

Where did you get this equation from?

Use excel to find the inverse of .01 to get the z value of -2.32635
and plug that into the equation for the z=(x-mu)/SD
