At your high school, you randomly surveyed male students to find that they play video games a certain amount of hours per week. What is the estimated population mean based on your sample?
A)
2.5 hours
B)
3 hours
C)
5 hours
D)
6 hours
Round the numbers and add them in your head. What is your estimate?
To find the estimated population mean based on the given sample, you need to calculate the mean of the hours played by the male students in the survey.
To do this:
1. Add up all the hours played by the male students:
4.5 + 6.25 + 3 + 2.5 + 7 + 6.75 = 30
2. Divide the total sum by the number of male students surveyed. In this case, there are six male students surveyed:
30 / 6 = 5
Therefore, the estimated population mean based on the sample is 5 hours.
So, the correct answer is option C) 5 hours.
