Chapter 4, Problem 1(choose chapter or problem)
Bottles filled by a certain machine are supposed to contain \(12 \mathrm{oz}\) of liquid. In fact the fill volume is random with mean \(12.01 \mathrm{oz}\) and standard deviation
\(0.2 \mathrm{oz}\)
a. What is the probability that the mean volume of a random sample of 144 bottles is less than \(12 \mathrm{oz}\)?
b. If the population mean fill volume is increased to \(12.03 \mathrm{oz}\), what is the probability that the mean volume of a sample of size 144 will be less than \(12 \mathrm{oz}\)?
