Problem of the Week: The Broken Eggs

Problem Statement: A farmer is carrying her eggs in a cart when she accidentally spills every one of them and they all break. She decides to go to her insurance agent, who asks her how many eggs she had. She’s not sure but she does know some information from various ways she tried to pack her eggs. She knows that when she put her eggs in groups of one, two, three, four, five, and six, there was always one egg left over. When she put them in groups of seven, there were no eggs left over. The task is to use this information to find out how many eggs the farmer had,

Process: In the process of attempting to solve this problem, I first figured out that I would have to find a number that leaves a remainder of 1 when divided by 2, 3, 4, 5, and 6 but is evenly divisible by 7. I noticed I only need to look at numbers that were a multiple of 7. 7/2= 3.1 7/3=2.1 7/4=1.3 7/5=1.2 7/6=1.1

When I divided all the numbers by 7 I saw that 2, 3, and 6 all leave a remainder of 1, but not 4 and 5. 14/2=7 14/3=4.2 14/4=3.2 14/5=2.4 14/6=2.2
I tried this again with the number 14 since it was a multiple of 7, but then I realized this would be too long of a process to do this with a different number over and over again. I thought about what I was doing and I knew that an even number wouldn’t work because they are divisible by 2. I realized that the number has to be an odd number and end with 1. I started to only look at numbers that ended with 1. 91 161 231

91 didn’t because 4 didn’t have a remainder of 1. 161 didn’t work because 2 didn’t have a remainder of 1. 231 didn’t work because 2 didn’t have a remainder of 1. Then I got to 301, and 2, 3, 4, 5, and 6 all had a remainder of 1 when I divided them.

Solution: My solution to this problem is the farmer had 301 eggs. This solution is correct because 301 is a multiple of 7, and which it is divided by 2, 3, 4, 5, and 6 it leaves a remainder of 1. I...

...depreciated straight-line over the five-year period and profits will be taxed at 25%. Assume all cash flows occur at the end of each year except where otherwise stated. What is the NPV of the project plant?
22. We can use the following spreadsheet to calculate a NPV of 6.352 billion RMB for the Ambassador China project. This calculation uses the following assumptions:
1. Calculations are done on a nominal basis, converting the salvage value estimate from a real to a nominal value (638 = 500(1.05)5) using the 5% inflation estimate; salvage = book value so no taxes are incurred on salvage.
2. Depreciation is calculated at [4,000 – 638 (salvage) ]/ 5 = 672.4 per year.
3. Cars sales occur in year 1 (there is some ambiguity here as the problem states it takes a year for the plant to become operational but also that sales will occur in the first year).
4. The tax shield in year 0 can be used to offset profits from other operations.
5. No working capital costs (this is unrealistic, but no figures are given).

...Practice Problems
Ch. 7, Practice Problem: 14
Evolutionary theories often emphasize that humans have adapted to their physical environment. One such theory hypothesizes that people should spontaneously follow a 24-hour cycle of sleeping and waking—even if they are not exposed to the usual pattern of sunlight. To test this notion, eight paid volunteers were placed (individually) in a room in which there was no light from the outside and no clocks or other indications of time. They could turn the lights on and off as they wished. After a month in the room, each individual tended to develop a steady cycle. Their cycles at the end of the study were as follows: 25, 27, 25, 23, 24, 25, 26, and 25.
Using the .05 level of significance, what should we conclude about the theory that 24 hours is the natural cycle? (That is, does the average cycle length under these conditions differ significantly from 24 hours?) (a) Use the steps of hypothesis testing. (b) Sketch the distributions involved, (c) Explain your answer to someone who has never taken a course in statistics.
Answer
Null hypothesis H0: = 24 hours Alternative hypothesis: H1: ≠ 24 hours
Df = 7 Critical t value = ±2.36 Sample Mean = 25
Standard deviation = 1.195 The test statistic used is
P-value = 0.049867231
Since calculated p-value 0.049867231 is slightly less than 0.05(significance level) therefore we reject the null hypothesis.
Because there is enough evidence to support the...

Question 3 - Imagine the worst possible reports from a system. What is wrong with them? List as many problems as you can. What are the consequences of such reports? What could go wrong as a result? How does the prototyping process help guard against eachproblem?
The incorrect data entered, or the software error of the system can cause the wrong result.
The problems can be
1. Wrong entry of data.
2. Inefficient Users to the system.
3. Software Error
The consequences are:
1. Wrong outputs.
2. Wrong decisions made.
3. Loss to the Company.
The whole process of the Company can go wrong as every repot generally are interconnected with each other. So if the output of any one is wrong the other reports may also show wrong results.
The prototyping process is where there is a systematic way of doing things. We have 4 phases in prototyping process Planning, specification, Design and Result. If all these are followed in a
