1. Suppose that a U.S. firm converts dollars into pounds in order to invest in a British enterprise in the U.K. A year later, the return on the investment is 12 percent in terms of pounds. If, during that period, the dollar appreciated against the pound, then the return on the investment in dollar terms would be A. greater than 12 percent. B. also 12 percent. C. less than 12 percent. D. dependent on the inflation rate, not the exchange...
For each variable of interest – Percent Time Asleep and Longevity – create a grouped frequency histogram. For each histogram, use a class width of 10; use a lower limit of 0 for Percent Time Asleep and 15 for Longevity. Each histogram must include an informative title, along with correct labels for both axes. For each histogram, include a paragraph that answers each of the following questions: Is the histogram symmetric, skewed to the left, or skewed to the right?...

You are studying an invasive insect species in the USA.
Understanding where invasive species comes from can help with
management (e.g., importation of native natural enemies for
biocontrol). The graph below shows output from a STRUCTURE analysis
of 10 microsatellite markers in 50 individuals taken from the
invasive US population, and the three native countries of origin,
Spain, France, and Italy. A-1pt) How many genetic groups, or
clusters, were identified in the analysis? Assuming you’ve completely
sampled the native range...

The data below are given in minutes: 62 48 50 47 52 40 34 35 41 45 28 42 28 45 60 49 38 37 23 24 35 59 58 30 32 48 40 45 59 55 52 65 20 47 50 47 56 62 50 30 1. 20-29 (a) (4 points) Find the range and the...
For the two variables of interest: Create a scatter plot with Percent Time Asleep as the independent variable x and Longevity as the dependent variable y. The plot must include an informative title, along with correct labels for both axes. Include a plot of the least-squares equation (see #5 below). Calculate the correlation coefficient and the coefficient of determination. Identify any data points on the scatter diagram that appear to be influential. Use Cook's Distance > (4⁄√n) as the criterion...
Part 1 In 1950 the U.S. had a population of 150 million and it was growing at 1.3% a year. Assume no net migration. (10 points total) a. In about how many years will it take for the U.S. population to double? (5 points) b. In 2010 U.S. population was 308 million. Calculate the average annual growth rate of the population over these 60 years. (5 points) Part 2 In year 1, a country has a population of 100 people;...
Queuing Exercise 1 Suppose you are operating a medical care center for a large factory. Workers come to the center if they become ill during working hours or if they have an accident requiring medical care. Table below is a history of 30 workers arriving at the clinic over a period of about eight hours. The left part of the table shows the actual times of arrival, when the patients actually started service (met with the doctor), and when they...
Starbucks enjoyed considerable success with its debit cards, which they sell for $5 to $500. Suppose a study of 25 randomly selected prepaid card purchasers is taken. Respondents are asked the amount of the prepaid card, the customer's age, the number of days per month the customer makes a purchase at Starbucks, the number of cups of coffee the customer drinks per day, and the customer's income. The data is below. How strong is the model? Explain in detail. Which...
