McGilla Golf has decided to sell a new line of golf clubs. The clubs will sell for $895 per set and have a variable cost of $431 per set. The company has spent $200,000 for a marketing study that determined the company will sell 80,000 sets per year for seven years. The marketing study also determined that the company will lose sales of 8,600 sets per year of its high-priced clubs. The high-priced clubs sell at $1,325 and have variable costs of $645. The company will also increase sales of its cheap clubs by 10,800 sets per year. The cheap clubs sell for $340 and have variable costs of $141 per set. The fixed costs each year will be $14,350,000. The company has also spent $1,500,000 on research and development for the new clubs. The plant and equipment required will cost $43,700,000 and will be depreciated on a straight-line basis. The new clubs will also require an increase in net working capital of $3,625,000 that will be returned at the end of the project. The tax rate is 25…
You have been hired as an intern to run analyses on the data and report the results back to Sarah; the five questions that Sarah needs you to address are given below.
Does there appear to be a positive or negative relationship between price and screen size? Use a scatter plot to examine the relationship.
Determine and interpret the correlation coefficient between the two variables. In your interpretation, discuss the direction of the relationship (positive, negative, or zero relationship). Also discuss the strength of the relationship.
Estimate the relationship between screen size and price using a simple linear regression model and interpret the estimated coefficients. (In your interpretation, tell the dollar amount by which price will change for each unit of increase in screen size).
Include the manufacturer dummy variable (Samsung=1, 0 otherwise) and estimate the relationship between screen size, price and manufacturer dummy as a multiple linear regression model.
Interpret the…
Does there appear to be a positive or negative relationship between price and screen size? Use a scatter plot to examine the relationship. How to take snapshots: if you use a MacBook, press Command+ Shift+4 to take snapshots. If you are using Windows, use the Snipping Tool to take snapshots.
Question 1: Determine and interpret the correlation coefficient between the two variables. In your interpretation, discuss the direction of the relationship (positive, negative, or zero relationship). Also discuss the strength of the relationship.
