if there's 3 counselors / 45 students.

3 counselors / 45 students = 1 counselor / 15 student

10 counselors multiplied by 15 students = 150 maximum students allowed.

C. The statement indicates that the true population percentage of people that prefer chocolate pie is in the interval 11%±3%.

Step-by-step explanation:

Data provided in the questions

Number of respondents = 1,000

Choose chocolate pie = 11%

margin of error = ±3 percentage points

Based on the above information,

The lower limit is

= 0.11 - 0.03

= 0.08

= 0.11 + 0.03

= 0.14

So based on the above computation, the option c is correct as it represents the true population percentage of people with respect to the chocolate pie preference
