Extracted text: The ruby-throated hummingbird beats its wings very quicky. Using a high-speed camera, an ornithologist was able to measure the wing beating speed (in beats per second) of 14 randomly chosen ruby-throated hummingbirds. The following are the measurements: 54.20, 51.99, 46.96, 50.91, 51.05, 45.75, 46.80, 50.57, 52.45, 48.41, 53.39, 51.97, 50.37, 51.41 Research has shown that wing beat speed is normally distributed. So, we assume that our sample comes from a normal population with an unknown mean of µ and an unknown standard deviation of o. . We would like to test whether the average wing beat speed of ruby-throated hummingbirds is greater than 50 beats per second. The null hypothesis is thus Ho:H=50 . We will test this against the alternative Ha . We want to test at the 6% level. Let x the sample mean and s = the sample standard deviation. a) What should the alternative hypothesis, Ha , be?
