Question 3
Question 9 of the questionnaire asked the students to disclose their weekly student
labour wage within the last month, for all student workers on campus. After
considering the data from the 35 students surveyed, you calculated the mean weekly
income of a student worker to be $350.00 weekly with a standard deviation of
$25.00.
a) Calculate u using a 95% confidence interval
b) The Principal of UBL claims that the average wage of a student worker is
$365.00. However, you the research wanted to find out if the mean wage is
different from $365.00. Therefore, a random sample of 35 students
produced a mean wage of $350.00, with a population standard deviation of
$30. Assume that the wage of all student workers in the University have a
normal distribution. Using the 5% significance level, can you conclude that
the Principal's claim is false?
i.
Perform a test of hypothesis using the p-Value approach - 4 steps
ii.
Perform a test of hypothesis using the Critical-Value approach - 5 steps
Note: Present your findings in the form of a report in no more than 10 lines.
