Random samples from the two airlines after a storm showed that 50 out of 100 of Airline 1's flights were delayed, and 70 out of 200 of Airline 2's flights were delayed.
-For a significance level of = 0.05, are the results statistically significant?
A) No, the results are not statistically significant because the p-value < 0.05.
B) Yes, the results are statistically significant because the p-value < 0.05.
C) No, the results are not statistically significant because the p-value > 0.05
D) Yes, the results are statistically significant because the p-value > 0.05.
