A researcher is interested in knowing if there is an association between the cause of flight delays and seasons.

Sub-research Questions and Hypotheses

H0: There is no association between seasons and the cause of flight delays

H1: There is an association between seasons and the cause of flight delays

Contingency table

	Non-Delay	Delay	Total
Spring	2900	682.99	3582.99
Summer	1514	427	1941
Fall	1505	256.99	1761.99
Winter	2757	527.01	3284.01
Total	8676	1893.99	10569.99

Chi-Square test:

Statistic	DF	Value	P-value
Chi-square	3	46.28382	<0.0001

Results

We reject the Null hypothesis as The chi-square statistic is 46.2832. The p-value is < 0.00001. The result is significant at p < .05. Thus, we conclude that seasons affect flight delays.

Question 1
