Categorize the following solvent recovery operation in terms of the waste management hierarchy. Discuss the pollution prevention features of this process. Determine whether this process is pollution prevention or not. Use both the federal definition and also the expanded definition adopted in this text. Process Description: The automotive industry uses robots to paint automobile bodies before attaching them to the chassis, and installing other components such as the drive train, lights, trim, and upholstery. In order to accommodate different colors, the paint lines must be flushed with a solvent and then re-charged with the new color paint. In the past, this solvent and paint residue was disposed of as hazardous waste or incinerated. The current process of spray painting automobiles uses a closed-loop solvent recovery process as outlined in the diagram below.

The Clap Chemical Company needs a large insulated stainless steel tank to expand its plant. A recently closed brewery has offered to sell their tank for $15,000 delivered. The price is so low that Clap believes it can sell the tank at any future time and recover its $15,000 investment.

Installing the tank will cost $9000 and removing it will cost $5000. The outside of the tank is covered with heavy insulation that requires considerable maintenance. This will cost $3500 in year 1 and increase by $1000 per year.

(a) Based on a 12% before-tax MARR, what life of the insulated tank has the lowest EUAC?

(b) When the insulated tank is replaced by another tank is the replacement’s economic life likely to be shorter or larger? Explain.

1. In a study of the effectiveness of physical exercise in weight reduction, a group of 16 people (randomly selected) engaged in a prescribed program of physical exercise for one month. Each subject’s weight (in pounds) is measured two times (before and after the physical exercise). The data can be found in the excel file Exercise with variables name Subject, Before, and After. At the 5% significance level, do we have sufficient evidence to conclude that the physical exercise program is effective? (21 points total)

Hint: The physical program will be considered effective, if before weight is greater than after weight. Difference = Before – After

A pharmaceutical company claims that its new drug reduces systolic blood pressure. The systolic blood pressure (in millimeters of mercury) for nine patients before taking the new drug and 2 hours after taking the drug are shown in the table below. Is there enough evidence to support the company's claim?

Let d=(blood pressure before taking new drug)−(blood pressure after taking new drug)d=(blood pressure before taking new drug)−(blood pressure after taking new drug). Use a significance level of α=0.01 for the test. Assume that the systolic blood pressure levels are normally distributed for the population of patients both before and after taking the new drug.

Step 1 of 5: State the null and alternative hypotheses for the test.

Ho: μd (=,≠,<,>,≤,≥) 0

Ha: μd (=,≠,<,>,≤,≥) 0

Step 2 of 5: Find the value of the standard deviation of the paired differences. Round your answer to two decimal places.

Step 3 of 5: Compute the value of the test statistic. Round your answer to three decimal places.

Step 4 of 5: Determine the decision rule for rejecting the null hypothesis H0 H0. Round the numerical portion of your answer to three decimal places.

Reject Ho if (t, I t I) (<,>) _____

Step 5 of 5: Make the decision for the hypothesis test.

Reject Null Hypothesis

Fail to Reject Null Hypothesis

If a perfectly competitive market moved toward monopolistic competition, we might expect

• less advertising.

• a smaller range of product differentiation, but a lower price.

• a greater range of product innovation and a lower price.

• a greater range of product differentiation, but a higher price.

You had to look for information regarding five recent innovations i.e. airbnb, telegram messenger, Apple, Skip the dishes and Uber.

1. Who is the founder and when did the innovation come about?
2. Why did the need arise for these innovations?

There are four areas in the Balanced Scorecard:

1. Financial Perspective
2. Customer Perspective
3. Internal Business Perspective
4. Innovation and Learning Perspective

• Please provide perspective for each.
• Insert two company goals for each perspective.
• Insert two measures or matrices for these two goals

1. Describe the ways technological innovation has changed since the 18th and 19th centuries.

2. The main factors influencing technological change.
