3. The average weekly allowance of students last year at a private high school was Php 800.00 per week, based on an enrollment of 2000 students. The junior high school students who did not have this information interviewed 50 students and found their average weekly allowance last year to be Php 700.00.

a.) Population:
b.) Sample:
c.) 2 Parameters:
d.) 2 Statistics:

A population is all the subjects, while a sample is only a portion of the subjects that is used to generalize to the population.

Parameters are measures on a population, while statistics are measures on a sample.

You have the n and mean for both.

a.) Population: The population in this case would be all the students at the private high school.

b.) Sample: The sample in this case would be the 50 students who were interviewed.

c.) 2 Parameters: The two parameters in this case would be the average weekly allowance of all the students at the private high school last year and the average weekly allowance of the junior high school students who were interviewed.

d.) 2 Statistics: The two statistics in this case would be the sample mean (Php 700.00) and the population mean (Php 800.00).

a) The population refers to the entire group of interest, which in this case is all the students at the private high school. The population size is given as 2000 students.

b) The sample refers to a subset of the population that is selected for study. In this case, the sample consists of the 50 junior high school students who were interviewed.

c) The two parameters in this scenario are:

1. Population mean (μ) - The average weekly allowance of all students at the private high school. It is given as Php 800.00 per week.

2. Sample mean (x̄) - The average weekly allowance of the 50 junior high school students who were interviewed. It is found to be Php 700.00.

d) The two statistics in this scenario are:

1. Sample size (n) - The number of students in the sample, which is 50.

2. Sample mean (x̄) - The average weekly allowance of the 50 junior high school students who were interviewed, which is Php 700.00.

a.) Population: The population in this scenario refers to all the students at the private high school. It includes all 2000 students.

b.) Sample: The sample in this scenario refers to the 50 students who were interviewed by the junior high school students. It is a subset of the entire population.

c.) 2 Parameters: Parameters are numerical values that describe characteristics of a population. In this case, the two parameters are:
1. Average weekly allowance of all the students at the private high school last year (Php 800.00).
2. Number of students in the population (2000 students).

d.) 2 Statistics: Statistics are numerical values that describe characteristics of a sample. In this case, the two statistics are:
1. Average weekly allowance of the 50 students interviewed (Php 700.00).
2. Number of students interviewed (50 students).
