A quality-control manager randomly selects 50 bottles of Coca-Cola that were filled on December 1 to assess the calibration of the filling machine. The average amount of Coca-Cola in those selected is 19.7 ounces. The sample in this study is A.all Coca Cola bottles filled on December 1 B. 19.7 ounces C. Average ounces for all Coca Cola bottles filled on December 1 D. 50 bottles of Coca Cola filled on December 1
Quality Control The quality-control manager of a bottling company wants to discover whether a filling machine over or underfills 16 -ounce bottles randomly. The following data represent the filling status of 20 consecutive bottles: A A A A A A A R R R R A A A A A A A R R A bottle is rejected (R) if it is either overfilled or underfilled. A bottle is accepted (A) if it is filled according to specification. Test the randomness of the filling machine in the way that it over- or underfills at the $\alpha=0.05$ level of significance.

The quality-control manager of a bottling company wants to discover whether a filling machine overor underfills 16 -ounce bottles randomly. The following data represent the filling status of 20 consecutive bottles: $A A A A A A A R R R R A A A A A A A R R$ A bottle is rejected (R) if it is either overfilled or underfilled and accepted (A) if it is filled according to specification. Test the randomness of the filling machine in the way that it overor underfills at the $\alpha=0.05$ level of significance.
