- An Extensive Study In Antarctica Concluded That The Mean Height Of Adult Emperor Penguins In The Wild Is 45 5 In Cassan 1 (34.29 KiB) Viewed 84 times
An extensive study in Antarctica concluded that the mean height of adult emperor penguins in the wild is 45.5 in. Cassandra believes that captive emperor penguins have a greater mean height due to better nutrition. To test this idea, she decides to conduct a one-sample t-test to see if the mean height of captive emperor penguins is greater than 45.5 in. She selects a simple random sample of 28 penguins from different zoos around the country and has each penguin measured. The summary statistics of the sample are given below. Sample size Sample mean * = 46.7 in Sample standard deviation 5 = 4.6 in = 28 The heights of emperor penguins are normally distributed, and there are no outliers in the sample. Construct the null and alternative hypothesis for the appropriate one-sample t-test for the mean height of captive emperor penguins. H: H:
