Question 1024658: An article in a newspaper states that the proportion of traffic accidents involving road rage is higher this year than it was last year, when it was 12%. If the information is based on population data. Determine whether hypothesis testing is needed? yes or no Answer by robertb(5830) (Show Source):
You can put this solution on YOUR website! No. The value obtained for this year is NOT a statistic (or estimate). It is a parameter, because it is based on population data. There is no randomness for a parameter.
