Test the claim given, identify null hypothesis, alternative hypothesis, test statistic, p-value or critical values, conclusion about the null hypothesis and final conclusion
Environmental concerns often conflict with modern technology, as is the case with birds that pose a hazard to aircraft during takeoff. An environmental group states that incidents of bird strikes are too rare to justify killing the birds. A pilot's group claims that among aborted takeoffs leading to an aircraft going off the end of the runway, 10% are due to bird strikes. A sample data consist of 74 aborted takeoffs in which the aircraft overran the runway. Among those 74 cases, 5 were due to bird strikes. Use a .05 level of significance to test the claim.
