The research firm LL Research collected data from 200 client businesses. They want to determine how the businesses compare among four variables:

2015 Profit in millions of dollars
2016 Profit in millions of dollars
2015-2016 Two-Year Change in Daily Average Customer Visits
Two-Year Average Number of Employees

Data collected for the sample of 200 businesses is contained in the file named Businesses, linked at the bottom of the page. Use all 200 data points.

Managerial Report
Prepare a report (see below) using the numerical methods of descriptive statistics presented in this module to learn how each of the variables contributes to the success of a client business. Be sure to include the following three items in your report.

1. Find descriptive sample statistics (mean, median, two quartiles Q1 and Q3, minimum, maximum, range, sample standard deviation, and coefficient of variation) for each of the four variables along with an explanation of what the descriptive statistics tell us about the client businesses.

2. Compute the percent change in profit from 2015 to 2016 for each business. Then use the z-score to determine which businesses were outliers with respect to percent change in profit.

3. Compute the sample correlation coefficient, showing the relationship between percent change in profit and each of the other two variables (2015-2016 Two-Year Change in Daily Average Customer Visits and Two-Year Average Number of Employees). Explain what the correlation coefficients tell us about the three pairs of relationships. Use tables, charts, or graphs to support your conclusions.

A small water pump is used for an irrigation project. The pump takes water in from a river at 10^oC, 100 kPa at a mass flow rate of 16.83 kg/s. The exit line enters a pipe that goes up to an elevation 26.15 mm above the pump and river, where the water runs into an open channel. Assume the process is adiabatic and that the water stays at 10 ^oC. Find the required pump work.

Determine whether the following scenarios indicate that the supply of the product is relatively elastic or relatively inelastic.

• oil producers are currently producing 30% below capacity
• a store that sells a good that cannot be stored easily
• a donut shop runs out of jelly-filled donuts this morning
• food trucks that can quickly relocate
• a golf course that has a limited amount of land to add new holes

Elastic Inelastic

A tank contains 400 gallons of brine (salt in solution) in which 125 pounds of salt has been dissolved. Freshwater (with no salt added) runs into the tank at a rate of 4 gallons per minute, and the stirred mixture is drained from the tank at the same rate. (1) Find the amount of salt in the tank after an hour. (2) How long does it take to reduce the amount of salt in the tank to 10 pounds?

Second stage of fusion:

Medium/high mass stars:

1. What will happen when the first fuel runs out? what will fuse next? (second stage of fusion)

2. what process do medium mass and high mass stars use to fuse the second stage of fusion?

3. What is degeneracy and how does it help medium mass stars to ignite the second stage of fusion?

Short runs

Short-run decision making consists of choosing among alternatives with an immediate or limited end in view. Short-term decisions sometimes are referred to as tactical, or relevant, decisions because they involve choosing between alternatives with an immediate or limited time frame in mind.

1. Suppose that a product can be sold at split-off for $5,000 or processed further at a cost of $1,000 and then sold for $6,400. Should the product be processed further?
