Explanation / Answer
We are allowed to do 1 question at a time. Post again for second question.
1) False
A statistic and a parameter are very similar. They are both descriptions of groups, like “50% of dog owners prefer X Brand dog food.” The difference between a statistic and a parameter is that statistics describe a sample. A parameter describes an entire population.
2) True
In addition, just because data is in numerical form, doesn't necessarily mean it can be added. Take phone numbers and social security numbers - both examples of quantitative data, yet, like qualitative data, they can't be added or subtracted.
