Assignment Task Two (300 words - 7 marks)

The coronavirus intervened Australia in early 2020.

On 12 May, the Morrison government issued an unprecedented progress report on the delayed budget, outlining the coronavirus pounding to the national economy and the huge outlay to deal with the pandemic.

What were the main issues presented? How do you think they would affect the economy, social and employment situation in the near future?

Given are five observations for two variables, and . xi2 15 7 22 19 yi50 48 58 11 23 d. Develop the estimated regression equation by computing the values of and using equations: (Enter negative values as negative figure) (to 2 decimals) e. Use the estimated regression equation to predict the value of y when . (to 2 decimals)

Consider the following two bonds: a 5-year and a 10-year bond, each with a 7% coupon. Both bonds currently sell at par and coupon payments are made annually (i.e., one coupon payment per year).

(a) What is the current price of each bond?

Hint: answer does not require calculations; read description of bonds carefully to determine what price must be (10 points) Suppose you buy the 10-year bond. One year later, interest rates decrease to 5%.

(b) What will be the new price of the bond? (30 points)

(c) What rate of return would you have earned on the bond over the one-year period? (20 points)

(d) Which bond will have a higher rate of return over the year, the 5-year bond or the 10-year bond? Why? (5 points).

You don’t need calculations for this one and will not be given any points for a numerical answer; respond based on your understanding of interest rate risk (price sensitivity) in bonds.

7. A particle of rest energy 800 MeV decays in its rest frame into two identical particles of rest energy 250 MeV. What are the kinetic energies (in MeV), momenta (in MeV/c), and velocities (in units of c) of the daughter particles?

Write the Verilog Code for the module to multiply two 7-bit numbers using the array multiplie

Western Home Inspections is a home inspection service that provides prospective homebuyers with a thorough assessment of the major systems in a house prior to the execution of the purchase contract. Prospective homebuyers often ask the company for an estimate of the average monthly heating cost of the home during the winter. To answer this question, the company wants to build a regression model to help predict the average monthly heating cost (Y) as a function of the average outside temperature in the winter (X1), the amount of attic insulation in the house (X2), the age of the furnace in the house (X3), and the size of the house measured in square feet (X4). Data on 20 homes has been recorded and is shown in Worksheet A2. The company wants to build a regression model to estimate the average monthly heating cost based on outside temperature, attic insulation, age of the furnace, and size of the house

a) Prepare a scatter plot showing the relationship between the heating cost and each of the independent variables.

b) If the home inspector wanted to build a regression model using only one independent variable to predict heating cost, which variable should be used?

c) Why?

d) How do you use the value of Significance F in the model with only one independent variable?

e) If the home inspector wanted to build a regression model using two independent variable to predict heating cost, which variable should be added to the model?

f) Why?

g) If the home inspector wanted to build a regression model using three independent variable to predict heating cost, which variable should be added to the two variable model?

h) Why?

i) If the home inspector wanted to build a regression model using four independent variable to predict heating cost, which variable should be added to the three variable model?

j) Why?

k) How do you use the value of Significance F in the model with more than one independent variable?

l) Does there appear to be any multicollinearity among the independent variables?

m) How can you tell if you have multicollinearity?

n) Which sets of variables indicate multicollinearity

o) Based on your best model, what is the expected average monthly heating cost for a home which has an average outside temperature of 45, 8 inches of attic insulation, a 7 year old furnace, and is 2000 square foot

1. Two communication devices are using a single-bit even parity check for error detection. The transmitter sends the byte 10101010 and, because of channel noise,

1. the receiver gets the byte 10011010. Will the receiver detect the error? Why or why not?
2. the receiver gets the byte 10111010. Will the receiver detect the error? Why or why not?
3. Compute the Internet checksum for the data block E3 4F 23 96 44 27 99 D3. Then perform the verification calculation.

You have purchased 30 shares of Games Inc. for $ 15 and 120 shares of Thrones Co for 721. Over the following three quarters, the companies earned the returns below Quarter 1 Quarter 2 Quarter 3 Games Inc. 20% 46% 44% Thrones Co. -20% -39% -12% What was the buy-and-hold return on your portfolio? Provide your answer in percent, rounded to two decimals, omitting the % sign.

4. To determine the effectiveness of a proposed public relations campaign, the senior vice president for customer relations for an automobile manufacturer asked seven consumers how much they liked the company (on a scale from 0 [do not like] to 50 [like very much]) before and after viewing the primary television advertisement of the campaign. Use the following data to test whether the consumers’ ratings of the company increased, on average, after viewing the television advertisement:

a. State the null and alternative hypotheses associated with the test.
b. If α = 0.05, what is the critical value of the associated test statistic?
c. What is the calculated value of the associated test statistic?
d. State your decision about the null hypothesis by comparing the critical and calculated values of the test statistic (Parts b and c).
e. Comment on the effectiveness of the primary television advertisement of the campaign.
