III. HYPOTHESIS TESTING



1. Research question

•. Design 7Qs  should change tardiness habits of HANU students or not

2. Assumption

. ôYesằ and «No» answers  qualitative data

•. Binominal distribution

•. Parameter of interest: (p)

•. More than 70% students coming late to school with equal or greater than 1 day

•. should change their habit



3. Data analysis





Sample size: n =100



(np=100x0.7=70>5; n(1-p)=100x0.3=30>5)







Z-test (upper tail test)







H0 : p<=0.7



Ha : p> 0.7







Significant level: α = 0.05







Critical value is Z0.05≈ 1.645. Reject H0 if Z>1.645



4.



Hypothesis testing procedure







Step 1: The null and alternative hypotheses

H0: p≤ 0.7

Ha: p> 0.7







Step 2: Test statistic

z=







(with q=1-p=0.3, p^=82/100=0.82)



Step 3: Significant level

α = 0.05







Step 4: Decision rule

Reject H0 if Z >1.645









Step 5: Value of test statistic

Step 6: Conclusion

Z = 2.62 > 1.645 , we reject H0.



P-value







With z = 2.62, we have:



p-value = P (Z > 2.62) = 1 -0.9956 = 0.0044

there is enough evidence at the level of significance α = 0.05

 Ha is true

there is enough evidence to conclude that more than 70% of Hanu students should change their late-for-class

habits



IV. Evaluation



1. Limitation

2. Implication

3. Recommendation

4. Conclusion



1. Limitation
