Solutions
Expert Solution
(1)
What you would hope(or expect) to find : The average number of hours a student spends per day for studies
(2)
Population:All the students of the College
(3)
Sample: A set of n students selected by method of sampling from the total population of N students of the college
(4)
The method of sampling: Stratified sampling.
Explanation:
Population Size = Total number of students of the entire college = N
Calculate Sample Size = n, by statistical mothods
Identify the Total number of various departments in the college = d
These d Departments constitute the strata of the sampling.
From each of the d department, select n/d students using Simple Random Sampling (SRS) technique
Thus, we have n students constituting the required sample.
(5)
The explanatory Variable: Students
(6)
The response variable: number of hours spent per day for studies
(7)
What you would hope(or expect) to find : The average number of hours a student spends per day for studies
