Q.13 In MacDonallds, an automated soda vending machine is used to fill glasses with soda. If the variance of the fill volume for each pour exceeds 1fl oz2 , then MacDonallds will make a loss from soda sale. A random sample of 30 bottles results in a sample variance of fill volume of s2=1.1fl oz2. Is there evidence in the sample data to suggest that MacDonallds has a problem with their soda vending machine? Use alpha = 0.01, and assume that fill volume has a normal distribution. (A) yes (B) no (C) not applicable (D) not applicable
