If the process standard deviation is known to be sigma 025


A machine that stuffs a cheese-filled snack product can be adjusted for the amount of cheese injected into each unit. A simple random sample of 30 units is selected, and the average amount of cheese injected is found to be x‾ = 3.5 grams.

If the process standard deviation is known to be σ = 0.25 grams, construct the 95% confidence interval for μ = the average amount of cheese being injected by the machine.
