A successful businessman is selling one of his fast food franchises to a close friend. He is selling the business today for $2,731,200.00. However, his friend is short on capital and would like to delay payment on the business. After negotiation, they agree to delay 3.00 years before the first payment. At that point, the friend will make quarterly payments for 18.00 years. The deal calls for a 6.48% APR “loan” rate with quarterly compounding. What quarterly payment will the friend make on the loan?

Create a small dataset of at least 5 observations and calculate the mean, median, mode, range, IQR and standard deviation (use Excel or StatCrunch). Add an outlier to your data and recalculate these measures. Which changed and by how much? Explain how this illustrates the idea of resistant measures. Please provide the data that you made up and the measures for your data before and after you added an outlier. Organizing the data into a table would be a great way to display all of this

Eight people were on a special diet to lose weight. We are testing to see if the diet actually works. We are going to do a Wilcoxon test. Please calculate the Wilcoxon T statistic. The critical value is 3. It is a two-tailed test with α = .05. Then come to a conclusion about the effectiveness of the diet. The data is:

                Before: 253         196         155         234         133         181         295         235

                After:     190         144         125         180         115         191         160         232

Suppose a recent college graduate's first job allows her to deposit $200 at the end of each month in a savings plan that earns 9%, compounded monthly. This savings plan continues for 11 years before new obligations make it impossible to continue. If the accrued amount remains in the plan for the next 15 years without deposits or withdrawals, how much money will be in the account 26 years after the plan began? (Round your answer to the nearest cent.)

The Grewals agreed to monthly payments on a mortgage of $336,000.00 amortized over 20 years. Interest for the first five years was 4.5% compounded semi-annually.

a. Determine the Grewals’ monthly payments.

b. Determine the balance owing after the 5-year term.

c. Before renewing for another term of 5 years at 4.3% compounded semiannually, the Grewals make an additional payment of $12,000. If they keep the same monthly payments, by how much will the amortization period be shortened?

Describe how high dietary sugar diets could promote insulin resistance. Be sure to 1) discuss how dietary sugar gets digested/absorbed 2) explain the fate of glucose into the muscle cell in insulin-sensitive states then how it could lead to insulin resistance as well as 3) identify how sugar interacts with exercise (before, during and immediately after) to foster movement. Highlight cell mechanisms and key hormones within answers when possible.

An oil exploration company purchases drill bits that have a life span that is approximately normally distributed with a mean equal to 88 hours and a standard deviation equal to 12 hours. (Round your answers to four decimal places.)

(a)

What proportion of the company's drill bits will fail before 79 hours of use?

(b)

What proportion will last at least 79 hours?

(c)

What proportion will have to be replaced after more than 97 hours of use?

• Bud Light ran a SuperBowl advertisement stating that it does not use corn syrup – in direct contrast to its competitors. The Bud Light marketing department wants to know the impact of the ad (IV) on consumer brand perceptions (DV). They therefore compare consumer perceptions of the brand collected before the SuperBowl with consumer perceptions of the brand collected after the ad was shown in the SuperBowl.
  • What form of study design is this?
  • Will the researcher be able to make claims about causality with this study?

1. Draw a well-presented and well-labelled supply and demand diagram to show the welfare effects of rent control.
2. Using your diagram from part (a) construct a well-presented table that shows the consumer surplus, producer surplus, total surplus and deadweight loss both before and after the rent control has been put in place.
3. According to your diagram has consumer surplus increased or decreased? Briefly explain consumer surplus has decreased or increased.

a) How much oxygen is required for drinking water?

b) How do the impurities (pollutants or other ions) in water affect aeration efficiency?

Question 2:  

A) How do you classify the settling types? Explain briefly.

B) Explain use of sedimentation units in water treatment (i.e. before or after which processes is sedimentation required).
