A researcher who is studying social media habits chose 900 SnapMode users at random at the beginning of 2016. Of these users, 82% said they sent at least three snaps a day. However, SnapMode executives say 63% of users sent at least three snaps a day. Which of the following statements is true? A. Eighty-two percent is a sample and 63% is a population. B. Eighty-two percent is a statistic and 63% is a parameter. C. Eighty-two percent and 63% are both statistics. D. Eighty-two percent is a parameter and 63% is a statistic. E. Eighty-two percent and 63% are both parameters.

B. Eighty-two percent is a statistic and 63% is a parameter

Step-by-step explanation:

Parameters are the values which are used to describe a given property for the entire population. On the other hand, statistics are the values which can be used to describe a given property for the sample.

In this scenario the 82% of users is pertaining to the 900 users sample and, therefore is a statistic while the 63% of users is pertaining to the whole population of the users and, thus, it is the parameter.

Therefore, the answer is option B. Eighty-two percent is a statistic and 63% is a parameter.
