A local high school's athletic department wants to calculate the proportion of students who have attended a girls softball game at the school.
Using student email addresses, the department randomly chooses 250 students and emails them the question. Of the 150 who respond, 22 answer they have attended a girls softball game. What is the best estimate of the population proportion of students who have attended a girls softball game at the school?
HELP PLEASE
A) 0.880
B) 22
C) 0.147
D) 0.110
22/150 = 0.147
To estimate the proportion of students who have attended a girls softball game at the school, you can use the data collected from the 250 students who were randomly selected and surveyed.
Among the 250 students, 150 responded to the survey, and 22 of them answered that they have attended a girls softball game.
To calculate the best estimate of the population proportion, you can use the formula:
Proportion estimate = (Number of students who have attended a girls softball game) / (Total number of students surveyed)
In this case, the number of students who have attended a girls softball game is 22, and the total number of students surveyed is 150.
Proportion estimate = 22 / 150 ≈ 0.147
Therefore, the best estimate of the population proportion of students who have attended a girls softball game at the school is approximately 0.147.
So, the correct answer is C) 0.147.
