Liquid detergent is filled into bottles in a machine that performs automatic filling. If the filling volume variance exceeds 0.01, a significant part of the bottles are filled incorrectly. From a random sample of 20 bottles taken, the filling volume was found to be the sample mean= 24 liters and the variance s2= 0.0153 litre2. α= 0.05 and it is known that the filling volume has a normal distribution. Which of the following is true for the hypothesis test to see if the bottles are filled incorrectly? Answer options group A)The alternative hypothesis is two-sided (≠-shaped). B)The corresponding test statistic is calculated as 29.07. C) The critical table value to be used is 1.729. D)The parameter of interest in the test is the anacuttle average.
