Answer: E. Statistic, because the data set of a sample of 1050 teenagers is a sample.
Step-by-step explanation:
In statistics , a parameter is a number that gives a measure of data for a whole population.
On the other hand a statistic is a number that gives a measure of data from a sample ( a subset of population).
Given : In a survey of a sample of 1050 teenagers , 17% said they like to watch soccer.
Since 1050 teenagers are representing the size of sample and 17% is the proportion of teenagers like to watch soccer.
Then, the underlined numerical value is a statistic.
