A stone thrown by an expert with a leather sling has an average speed of 140 kilometers per hour with a standard deviation of 20 kilometers per hour. David wants to test to see if the average speed of a stone that he throws from his sling is greater than 140 kilometers per hour. He sets up a hypothesis test with the following hypotheses: H0 : u = 140 Ha : u > 140 He uses a level of significance of cx = 0.05. He takes a simple random sample of 50 of his throws from the past year and computes x = 142 kilometers per hour. David's p-value was 0.24, and he failed to reject the null hypothesis. What type of error could David have committed? Group of answer choices Type I error Type II error David could not have committed a Type I or Type II error
