Q1) Let the sample data below.
Assume we want to test give hypotheses for the data:
Ho: u< or equal to 40
Ha: u>42
Compute mean x and standard deviation s of data above.
i) Calculate Ho by using traditional/classical method.
ii) Find out the critical value for a = 0.05
iii) Test Ho by using traditional/classical method
iv) Write down the decision based on results of test.
v) Had you used p-value method of hypothesis testing, determine the p-value have been?
