Chapter 13.2, Problem 15E
The largest commercial fishing enterprise in the southeastern United States is the harvest of shrimp. In a study described in the paper “Long-term Trawl Monitoring of White Shrimp, Litopenaeus setiferus (Linnaeus), Stocks within the ACE Basin National Estuariene Research Reserve, South Carolina“ (Journal of Coastal Research [2008]: 193–199), researchers monitored variables thought to be related to the abundance of white shrimp.
One variable the researchers thought might be related to abundance is the amount of oxygen in the water. The relationship between the mean number of white shrimp caught in a single outing and oxygen saturation was described by fitting a regression line using data from 10 randomly selected offshore sites. Computer output is shown below.
- a. Is there convincing evidence of a useful linear relationship between the mean number of shrimp caught and oxygen saturation? Explain. (Hint: See Example 13.5.)
- b. Is the relationship strong? Explain why or why not.
- c. Construct a 95% confidence interval for β and interpret it in context. (Hint: See Example 13.4.)

What is the 95% confidence interval of the difference of means,
? Round your answers to two decimal
places.
A 2009 study to investigate the dominant paws in cats was described in Animal Behaviour (Volume 78, Issue 2). The researchers used a random sample of 42 domestic cats. In this study, each cat was shown a treat (5 grams of tuna), and while the cat watched, the food was placed inside a jar. The opening of the jar was small enough that the cat could not stick its head inside to remove the treat. The researcher recorded the paw that was first used by the cat to try to retrieve the treat. This was repeated 100 times for each cat (over a span of several days). The paw used most often was deemed the dominant paw (note that one cat used both paws equally and was classified as "ambidextrous"). Of the 42 cats studied, 20 were classified as "left-pawed".
Provide an interpretation of your 99% confidence interval in the context of this data situation.

- Cheek teeth of extinct primates. The characteristics of cheek teeth (e.g., molars) can provide anthropologists with information on the dietary habits of extinct mammals. The cheek teeth of an extinct primate species were the subject of research reported in the American Journal of Physical Anthropology (Vol. 142, 2010). A total of 18 cheek teeth extracted from skulls discovered in western Wyoming were analyzed. Researchers recorded the dentary depth of molars (in millimeters) for a sample of 18 cheek teeth extracted from skulls. These depth measurements are listed in the accompanying table. Anthropologists know that the mean dentary depth of molars in an extinct primate species— called Species A—is 15 millimeters. Is there evidence to indicate that the sample of 18 cheek teeth come from some other extinct primate species (i.e., some species other than Species A)?

Our data contains the following variables: hours = a woman’s number of hours of work per week kids = a woman’s number of children living at home lockdown = a dummy variable equal to one if the woman is living in an area under a lockdown order and 0 is she is living in an area not locked down.
