The World Health Organization Recorded a Total of 148 Cases

The World Health Organization recorded a total of 148 cases of parasitic Guinea worm infection worldwide in 2013, down from millions of cases just two decades ago. The sharp decline in infections is attributed primarily to water filtration using a simple cloth. A research paper found that, in 10 replications, a polyester cloth filtered 100% of the organisms carrying the Guinea worm larvae. Which of the following is correct about the numerical summaries 148 and 100%?

A) 100% is a parameter and 148 is a statistic.
B) 148 is a parameter and 100% is a statistic.
C) Both 148 and 100% are statistics.
D) Both 148 and 100% are parameters.
