A movie theater is testing out their soda machine to see if it is dispensing the same amount for their “small-sized” sodas

 A quality control engineer is concerned that the machine is under filling the cups. He draws a random sample of 8 cups and records the following amounts:

12.12     11.35     11.51     11.86     11.75     11.45     11.92     12.22

A) Construct a 90% confidence interval for 𝝁

B) The soda machine is supposed to be filling the cups with 12 ounces of soda. Based on your interval, is the machine under filling the cups? Explain your reasoning.
