A 6 inch diameter water main in your town has become very rough due to rust and corrosion. It has been suggested that the flowrate through this pipe can be increased by inserting a smooth plastic liner into the pipe. Although the new diameter will be smaller, the pipe will be smoother. Will such a procedure produce a greater flowrate? List all assumptions and all calculations.

IMPORTANT NOTE: Please have the answer complete, CLEAR and computer generated!!

Suppose we would like to determine if the typical amount spent per customer for dinner at a new restaurant in town is more than $20.00. A sample of 49 customers over a three-week period was randomly selected and the average amount spent was $22.60. Assume that the standard deviation is known to be $2.50. Using a 0.02 level of significance, would we conclude the typical amount spent per customer is more than $20.00?

You purchase a $225,000 town home and you pay 20% down. You obtain a 30 year fixed rate mortgage with an annual interest rate of 3.75%. After 20 years you refinance the mortgage for 10 years at a 3.25% annual interest rate. After you refinance what is the new monthly payment to the nearest dollar? 1.) 797 2.)814 3.) 932 4.)1,335 5.) 1,500

Here's a slightly more realistic example

• You live in a town with an affluent side and a not-so-affluent side.
• The folks on the affluent side have annual incomes in the $80,000 to $120,000 range while the not-so-affluent side ranges from $20,000 to $40,000.
• Therefore, the median and the mean of the affluent demographic is roughly $100,000 while that of the not-so-affluent side is roughly $30,000.
• The number of families in the affluent demographic is slightly larger than the number of families on the other side. As such, the median family income is about $100,000 for the entire town while the mean income is closer to $65,000.

Due to mismanagement of funds and a complete lack of fiscal oversight, a significant tax levy is necessary to close a budget shortfall and prevent default on several municipal loans. The town council seeks to impose a universal, one-time tax levy on all families to fix the budget problem. They propose a one-time tax of $5,000 on each family in the town. The politicians state, “The Median Family Income in this town is $100,000. Surely, a one-time 5% tax is a small price to pay to shore up our town’s funds and fix things once and for all”.

Let's say you're a member of the town council, and a TV reporter asks you the following questions:

1. What percent of an affluent family's earnings is the $5,000 tax?
2. What percent of a not-so-affluent family's earnings is the $5,000 tax?
3. Is the tax fair to all families in the town?
4. What is misleading about the politician's statement, if anything?

In 2000, the percentage of adults in a certain town who drove an SUV was 53%. In 2005, in a random sample of 100 people from this town, 45 said that they drive an SUV. At the 10% level of significance, use the critical-value method to determine if the percentage of adults in this town who drive an SUV has changed from the 2000 percentage. Correctly state a) your conclusion about what to do with H0 AND b) your conclusion about the claim that is being made.

A recent article reported that a job awaits only one in three new college graduates. The major reasons given were an overabundance of college graduates and a weak economy. A survey of 200 recent graduates from your school revealed that 80 students had jobs. At the .01 significance level, can we conclude that a different proportion of students at your school have jobs? Use critical value approach.

1. There are 700 students in a middle school. At the end of the year, there is a school-wide drawing for 3 identical new bicycles.

1. Is this a combination or a permutation? Why?

2. How many possible outcomes of the drawing are there?

Suppose that bicycles in the drawing are not identical: One bike is plated in gold and valued significantly higher than the other two, the silver and bronze bikes, with the bronze being the cheapest.

3. Does this change the number of possible outcomes of the drawing? Explain.

Victor and Jasmine Gonzalez were discussing how to plan for their three young sons’ university education. Stephen turned 12-years old in April, Jack turned 9 in January, and Danny turned 7 in March. Although university was still a long way off for the boys, Victor and Jasmine wanted to ensure enough funds were available for their studies.

Victor and Jasmine decided to provide each son with a monthly allowance that would cover tuition and some living expenses. Because they were uncertain about the boys’ finding summer jobs in the future, Victor and Jasmine decided their sons would receive the allowance at the beginning of each month for four years. The parents also assumed that the costs of education would continue to increase.

Stephen would receive an allowance of $1000 per month starting September 1 of the year he turns 18.

Jack would receive an allowance that is 8% more than Stephen’s allowance. He would also receive it at the beginning of September 1 of the year he turns 18.

Danny would receive an allowance that is 10% more than Jack’s at the beginning of September of the year he turns 18.

Victor and Jasmine visited their local bank manager to fund the investment that would pay for the boys’ allowances for university. The bank manager suggested an investment paying interest of 4.0% compounded monthly, from now until the three boys had each completed their four years of education. Victor and Jasmine thought this sounded reasonable. So on June 1, a week after talking with the bank manager, they deposited the sum of money necessary to finance their sons’ post-secondary educations.

Questions
a. How much allowance will each of the boys receive per month based on their parents’ assumptions of price increases?
b. (i) How much money must Victor and Jasmine invest for each son on June 1 to provide them the desired allowance?
(ii) Create a timeline of events for each of the sons.
(iii) What is the total amount invested on June 1?
