Construct a histogram of your empirical data using eight bars and then five bars. For consistency's sake, for eight bars use the class width of 0.125. So, your first bar will be 0.000-0.124, your next bar will be 0.125 - 0.249, etc. For five bars, use the class width of 0.2. So, your first bar will be 0.00-0.19, your next bar will be 0.2-0.39, etc. Upload both pictures of your histograms. ***Below are my 50 random numbers. What do I need to show? I am confused on what exactly I need to show. Can you help me on these?

A Portland Cement Concrete (rigid) pavement is to be designed using AASHTO empirical design method. The pavement should have an 8" granular sub-base having elastic modulus (E_sb) of 50x10³ psi. The resilient modulus of the subgrade is 5000 psi, and lying just 5 feet above rock strata (bed rock).

(a) Determine the design k value, assuming loss of support factor (LSF) of 2.

(b) Use the k value obtained from (a) to determine the thickness of the rigid pavement.  

Assume concrete elastic modulus (E_c) = 5 x 10⁶ psi , Modulus of rupture (Sc) = 650 psi, load transfer factor J = 3.2, drainage coefficient C_d = 1.0, present serviceability loss ∆PSI = 4.2 — 2.5 = 1.7, reliability R = 95%, standard deviation S_o = 0.29, and total ESAL W₁₈ = 5.1 x 10⁶.

QUESTION 5

Never read an empirical paper without a calculator. Check the numbers and the percentages. Do the number of subjects in the tables of results add up to the numbers the researchers said they enrolled at the beginning of the study? All of this will help you understand what the authors did in conducting their study. Two other important tools to have at hand when critically reading a research paper are the highlighter tool in your word processor or spreadsheet for marking important sections of the paper and a sticky note or comment tool in your software for writing notes and questions on the paper itself.

True

False

QUESTION 7

A review of any body of literature actually consists of four fundamental tasks, after the subject of the review has been decided these include writing a synthesis that includes only the content and never a critical analysis of these materials.

True

False

QUESTION 10

A more sophisticated strategy for indexing the contents of an expanding Documents folder is the Matrix Indexing System. The simpler approach is this tracking system. Whichever system you use, the benefits accrue only if you keep the list up to date.

True

False

Empirical studies have provided support for
the belief that an ordinary share’s annual
rate of return is approximately normally
distributed. Suppose that you have invested in
the shares of a company for which the annual
return has an expected value of 16% and a
standard deviation of 10%.
a Find the probability that your one-year
return will exceed 30%.
b Find the probability that your one-year
return will be negative.
c Suppose that this company embarks on
a new, high-risk, but potentially highly
profi table venture. As a result, the return
on the share now has an expected value
of 25% and a standard deviation of 20%.
Answer parts (a) and (b) in light of the
revised estimates regarding the share’s
return.
d As an investor, would you approve of the
company’s decision to embark on the new
venture?

1. The General Social Survey polled a sample of 209 people aged 18-30 in the year 2000, asking them how many hours per week they spend on the internet. The sample mean was 6.75 with a standard deviation of 7.71. A second sample of 541 people aged 18-30 was taken in 2006. For this sample, the mean was 7.34 and standard deviation of 10.93. Assume these are simple random samples from populations of people aged 18-30. Can you conclude that the mean number of hours per week spent on the internet increased between 2000 and 2006?

a. Do the hypothesis test with α=0.05 significance level.

b. Construct a 95% confidence interval for the difference in mean number of hours spend per week on the Internet between 2000 and 2006.

c. Calculate the Margin of Error for 95% confidence level.

You are given four samples (approximately 10% oil and 90% water) all of which have been processed to have an average fat droplet size of 1.57 microns in each. They were prepared in the following manner and have different rates of separation:

Sample 1 was processed with a standard homogenizer at 2000 psi with a velocity of separation being .3 m/s

Sample 2 was processed with a standard homogenizer at 2000 psi (1^st stage) and 500 psi (2^nd stage) with a velocity of separation being .1 m/s

Sample 3 was processed with a microfluidizer with a velocity of separation being .4 m/s

Sample 4 was processed with a standard homogenizer at 2000 psi with a velocity of separation being .5 m/s (This sample had 0.5% of an emulsifier added.) THE RATE IS NOT A TYPO.

Why are the rates of separation different?                                                                           

1. Jane is 40 years old and has $ 50,000 in her investment account equally spread . And she plans to put in $ 2000 every year in each of the two funds . (15 % of this grade)

• Fund A :
  1. Current amount : $ 25,000
  2. Historical performance , 10 year average : 8.5 %
  3. Fund beta : 1.2
  4. $2000 added ever year
• Fund B :
  1. Current amount : $ 25,000
  2. Historical performance , 10 year average : 4 .5 %
  3. Fund beta : 0.5
  4. $2000 added ever year

1. Using ten year average performance, calculate amount in each fund, and total portfolio at end of 10 years, 20 years and 30 years
2. Calculate portfolio beta at 10 year, 20 years and 30 years ( Hint : Portfolio beta is weighted average beta . Covered in Std deviation and Beta lectures…. recorded lecture for Beta)

TVM Consulting bought new building for its headquarters in the year 2000. The purchase cost was 228197 dollars and in addition it had to spend 22004 dollars adapting the space for its services. The building has been in use since June 21st, 2000. TVM Consulting forecasted that in 2030 the building would have a net salvage value of $100,000. Using the US Straight Line Depreciation Schedule, estimate the total value of depreciation recorded in the accounting books if TVM consulting decides to sell the building on April 15th , 2004 (i.e. summation of all annual depreciation amounts recorded throughout the years of usage). (note: round your answer to the nearest cent and do not include spaces, currency signs, or commas)

CORRECT ANSWER: 24592.16

I am assuming the date of purchase is June 21st, 2000. This is all of the information given.

Write Program in C:

Write a program that: program starts; declares and initializes to 7.25% constant float variable NJSALES_TAX; declares and initializes to 1000 an integer variable total; declares and initializes to zero a float variable grand_total; prompt and input on new line total; calculate grand_total to equal total plus (total*NJSALES_TAX); if grand_total <= 1000 print on new line “Grand total is less than or equal to 1000 it is $” and the grand_total to two decimal places; else if grand_total between 1000 <= 2000 print on new line “Grand total is more than 1000 less than or equal to 2000 it is $” and the grand_total to two decimal places; else print on new line “Grand total is greater than 2000 it is $” and the grand_total to two decimal places; just before ending print on new line “Program finished!” then terminate program.
