I am conducting research on the relationship between the number of flights per quarter versus the number of runway incursions. The data collected and organized is broken into quarters within each fiscal year. My proposed hypotheses are:

Ha: There is statistical significance between the number of runway incursions between FY 2018 and FY 2021 and the number of annual flights.

Ho: There is no statistical significance between the number of runway incursions between FY 2018 and FY 2021 and the number of annual flights.

Fiscal Year Total Number of Flights Quarters Q1-Q4
18-1 1952648 403
18- 2 2152072 482
18-3 2203077 493
18-4 2092178 440
19-1 2004939 382
19-2 2191370 445
19-3 2243908 486
19-4 2156495 419
20-1 1977447 295
20-2 699518 217
20-3 1226146 330
20-4 1260181 318
21-1 1307735 296
21-2 1697945 485
21-3 1936988 476
21-4 1245026 398

The results I got from running a simple linear regression with a significance level of 0.05 set are as follows:

Simple linear regression results:

Dependent Variable: Quarters Q1-Q4 Independent Variable: Flights FY 18 - 21 Quarters Q1-Q4 = 286.25992 + 0.000068146655 Flights FY 18 - 21 Sample size: 16 R (correlation coefficient) = 0.51227147 R-sq = 0.26242206 Estimate of error standard deviation: 75.070936

Parameter estimates:

Parameter Estimate Std. Err. DF 95% L. Limit 95% U. Limit
Intercept 286.25992 53.390023 14 171.74971 400.77013

Analysis of variance table for regression model:

Source DF SS MS F-stat P-value
Model 1 28071.402 28071.402 4.9810448 0.0425
Error 14 78899.035 5635.6454
Total 15 106970.44

Would you make any recommendations on organizing the data and does the outcome make sense? The resultant R (correlation coefficient) = 0.5122 with a p-value of 0.0425 is less than 0.05 which means that we reject the null hypothesisthat there is no statistical significance between the number of runway incursions between FY 2018 and FY 2021 and the number of annual flights.
