Say whether this or that example describes the use of descriptive or inferential statistics. 1. Take a sample of batteries and test them to determine the average shelf life - use the sample average to reach conclusions about all batteries of this type. Management can then make labeling and advertising claims. They can compare these figures to the shelf-life of competing batteries. - select an option 2. Total number of worker hours per plant per week - help management understand labor costs, work allocation, productivity, etc. - select an option 3.
