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

Poor self awareness on the matter

2. Implication
