2. An entomologist writes an article in a scientific journal which claims that fewer than 10 in ten thousand male fireflies are
able to produce light due to genetic mutation. Identify the Type I error for the test. (2) a) The error of failing to reject that the true proportion is at least 10 in ten thousand when it is actually less than 10 in ten thousand. b) The error of rejecting that the true proportion is less than 10 in ten thousand when it is actually less than 10 in ten thousand. c) The error of rejecting that the true proportion is at least 10 in ten thousand when it is actually at least 10 in ten thousand. d) The error of failing to reject that the true proportion is less than 10 in ten thousand when it is actually is at least 10 in ten thousand.

These perforations allow for the continuous flow of water into the xylem vessels.The xylem tracheids are long, narrow, tubelike cells. The walls of tracheids are thick and hard.
