(a)
To explain: The population in the given survey was conducted to know whether school students favour the school’s new dress code.
The population in the given survey is the total number of students in the school.
Given:
A survey was conducted where every tenth student who enters the school building is asked whether they favour the new dress code. Sample statistics say 54$ favour and 42% oppose and 4% have no opinion about the dress code.
Concept used:
The population is the total set of objects in the study.
Explanation:
The study was conducted to know whether students favour the new dress code or not. Thus the population is the total number of students in the school.
(b)
To explain: The sample considered in the given survey was conducted to know whether school students favour the school’s new dress code.
Every tenth student who enters the school building on that particular day will be the sample.
Explanation:
From the population, a sample of students is selected for the study. Here every tenth student entering the school is surveyed about the new dress code. Thus the sample is the total of all students who entered the school building on that particular day.
(c)
To explain: The general conclusion that can be made about the population.
The sample statistics can be used to make a conclusion that a little over half of the students support the new dress code.
With reference to the sample statistic data, the percentage of students who favour the new dress code is 54%. The sample statistic can be used to generalize the conclusion with respect to the population that slightly more than half of students support new dress code.
