i?m : 0/1 An entomologist writes an article in a scientific journal which claims that fewer than 16 in ten thousand male fireflies are unable to produce light due to a genetic mutation. Assume that a hypothesis test of the given claim will be conducted. Identify the type I error for the test. a. The error of rejecting the claim that the true proportion is at least 16 in ten thousand when it really is at least 16 in ten thousand. ng �� b. The error of failing to reject the claim that the true proportion is at least 16 in ten thousand when it is actually less than 16 in ten thousand. Kh ng d ng c. The error of rejecting the claim that the true proportion is less than 16 in ten thousand when it really is less than 16 in ten thousand. Kh ng d ng Kh ng d ng i?m: 0/1. Question 138 i?m : 0/1 Those methods involving the collection, presentation, and characterization of a set of data in order to properly describe the various features of that set of data are called a. the scientific method.

Question 140 i?m : 0/1 The distances traveled (in miles) to 7 different swim meets are given below:12, 18, 31, 46, 69, 71, 85.Find the median distance traveled. Kh ng d ng i?m: 0/1. Question 141 i?m : 0/1 We have created a 95% confidence interval for $$\mu$$ with the result (10, 15).
