Simulation 5 Use the attached template to build an Excel spreadsheet for a purchase of $1,000,000 face value, 6% 5-year bond with interest payments every 6 months. Market interest rate is 5%.

Include the following items: Inputs: Bond initial purchase amount Stated Interest Rate Maturity in Years Number of payments/year Market interest rate Calculations section 1: --Fair value with separate calculations for interest and principal --Discount or premium --Record the journal entry required when the bonds are purchased. Calculations Section 2: --Amortization schedule for each interest payment received (investment revenue). Use the general ledger accounts of cash, discount or premium, bonds payable and interest expense. (Similar to illustration 12-2)

Set up the spreadsheet consistent with journal entries necessary to record each interest payment received and related amortization. Also show the remaining principal and discount/premium at each interest receipt. NOTE: At the end of the bond investment term, the discount/premium account should be zero. Make sure you use as many formula as possible in the Excel spreadsheet so that your spread sheet will recalculate automatically when the inputs are changed.

QUESTION 2:

When a manufacturing process is operating properly, maximum length of a certain part must be 25cm. The lengths which are more than 25cm are scrap. If the proportion of scrap is more than 0.171255, then a modification of the process is needed to reduce this amount. On one production run, a random sample of 50 consecutive parts are selected and the following lengths are observed.

Cobalt has spilled into a pond and our task is to precipitate it out.

Your task is to choose a precipitation agent. It has been found that the cobalt is in the +2 state. After consulting your handy textbook, you see that the possible precipitants are carbonate, sulfide and hydroxide ions. Remember that the pH of the pond is already set.  

Based on what you know about equilibria, write the pertinent chemical reactions that would occur for each of the possible precipitants (not the precipitation reaction). Does the pH of the solution matter?  

a) Co+2 titrated with Na2S

b) Co+2 titrated with Na2CO3

c) Co+2 titrated with NaOH

In a sample of 100 Oklahoma public schools, it was found that Oklahoma spends 8,097 dollars per pupil per year, with a standard deviation of 220 dollars. The population average of three surrounding states (Arkansas, Kansas, and Missouri) is 10,039 dollars. (these numbers are accurate – taken from most recent available data for 2016 https://ballotpedia.org/Public_education_in_Oklahoma.). Is per pupil spending for all Oklahoma schools less than the surrounding state population average? If you had to voice your concerns to your elected representative about per pupil spending in Oklahoma public schools, what would you tell them?
