Describe in detail a “business process”from Mandarin Hotel.

An individual wanted to determine the relation that might exist between speed and miles per gallon of an automobile. Let X be the average speed of a car on the highway measured in miles per hour and let Y represent the miles per gallon of the automobile. The following data is collected: X 40 45 45 50 50 52 55 55 Y 28 26 25 22 20 20 17 15

a. In the space below, draw a scatterplot of the bivariate data set.

b. What is the value for r? Interpret this value, would you say that the correlation is positive or negative? Strong or Weak? How do you know?

c. From the regression equation given above, what value is the slope of the line? Interpret this slope, what does it tell us about the relationship between average speed and miles per gallon?

d. Predict the miles per gallon of a car traveling 61 miles per hour. e. Predict the average speed of a car whose fuel mileage is 25 miles per gallon. f. Find r squared. What does this statistic tell us about between average speed and miles per gallon?

1) Business travel demand for hotel rooms in an area is 80% and vacation travel demand 20%. Annual compound business travel growth is 7% and vacation travel 10%. Total composite growth rate is 7.6%.

2) The business traveler component of demand for hotel rooms in an area is 80% and has been growing at 7% a year. Composite growth rate is 56%.

You are trying to decide whether to take a vacation. Most of the costs of the vacation (airfare, hotel, and forgone wages) are measured in dollars, but the benefits of the vacation are psychological. How can you compare the benefits to the costs? Compare the airfare and hotel costs of the vacation to the foregone wages. Determine the benefits of what you give up by going on the vacation, and compare them to the benefits of going on the vacation. Get a degree in psychology.

1. How would you calculate the population size of a species of plant? How would you calculate the population size of a species of mice?

2. Practice: A biologist originally marked 40 butterflies in a park. Over a period of 30 days, butterfly traps caught 200 butterflies. Of the 200 captured, 8 were found to have tags. Based on this information, what is the estimated population size of the butterflies in the Park?
