Construct  90%, 95%, and 99% confidence intervals for the population mean, and state the practical and probabilistic interpretations of each. Indicate which interpretation you think would be more appropriate to use. Explain why the three intervals that you construct are not of equal width. Indicate which of the three intervals you would prefer to use as an estimate of the population mean, and state the reason for your choice.

In a length of hospitalization study conducted by several cooperating hospitals, a random sample of 64 peptic ulcer patients was drawn from a list of all peptic ulcer patients ever admitted to the participating hospitals and the length of hospitalization per admission was determined for each. The mean length of hospitalization was found to be 8.25 days. The population standard deviation is known to be 3 days.

For each confidence interval indicate

b) Error,

You have discovered a new species of vampire bat in South America (which you have named Desmodus knoxensis!), and you wish to answer several questions about its behavior.

Given the fact that D. knoxensis females and juveniles roost together in hollow trees like other vampire bats, you hypothesize that vampire bat roosts act as information centers, a hypothesis that requires FOUR pieces of evidence (list them below). Based on your knowledge of a related vampire bat species (D. rotundus), what evidence is ALREADY AVAILABLE to support this hypothesis or what evidence would STILL BE REQUIRED (give details for both)? (12 points)

Evidence required for Information Center Hypothesis / Available or not? (Explain below each required piece of evidence: whether it is available and what observations support this hypothesis in D. rotundus. If not available state what observations would be needed to support the required evidence.):

The coronavirus crisis brought the U.S. economy to a halt, and although economic activity has partially resumed, many anticipate a contraction in gross domestic product for 2020 (particularly between April and June). Refer to section 10-3 (The Components of GDP) from our textbook, and explain which of those components you believe is contributing the most to the downturn in economic activity?

Explain your position using proper economic theory as a good foundation for your response, but making sure your own opinion and evaluative remarks stand out (i.e.: your opinion and remarks need to make economic sense!)
