Question

In a public school, 3,500 students are studying. A survey has been conducted among 350 students to find the mean height of the students. If the mean height is 5 feet 5 inches, what is the estimate of the population parameter?

 

A. 5 inches and 5 feet
B. 5 feet and 8 inches
C. 5 feet
D. 5 feet and 5 inches

Answer 1

The estimate of the population parameter is 5 feet and 5 inches, or D. Assuming the survey was a random sample of the 3,500 students, we can reasonable infer that the the chosen 350 students is a accurate representation of the entire student body. Since the mean, or average, height of the surveyed students was 5 feet and 5 inches, we can further infer that this height is also an accurate representation of the student body. Therefore showing that D is correct.
