Perform a linear regression on this data set

Be sure to plot the data and plot and include various graphs that would help determine if the data is normally distributed (which is an assumption of ordinary least squared regression).

At the 0.05 significance level is there evidence of a relation between assessed value and heated area of house?

Your company plans to sell 2000 ounces of silver next week decides to use silver futures contracts to create a minimum variance hedge. Each futures contract has 125 ounces of silver attached. The spot and futures prices for silver the day your company opened its position were $16/ounce and $20/ounce, respectively. The table below shows both spot and futures price changes over a three day period.

1. Find the standard deviation of change in the spot price. Round intermediate steps to four decimals.

2.Find the covariance between changes in the spot price and changes in the futures price. Round intermediate steps and your final answer to four decimals. Enter your answer in decimal format (EX: .XXXX).

3.Find the correlation coefficient between the spot and futures price changes. Round intermediate steps to four decimals.

4. How many futures contracts will you need to minimize your portfolio's risk? Round your final answer to the nearest whole number. Do not use words when entering your response.

I want to know how to solve this step by step please! :)

In the early 2000’s, DHL expanded its worldwide air express package delivery service to the US market in direct competition with UPS and FedEx. After several years and more than one billion dollars in losses, DHL admitted defeat in 2008 withdrawing from most US markets while shedding some 15,000 US jobs.

Think back to DHL announcement of its intention to enter the US market. Various stakeholders would greet the prospect of increased competition differently.

In this discussion forum, address the following:

Choose two of the following stakeholder groups, preferably with opposing views, and explain from their perspective why you oppose or support the entry of DHL in the US domestic market:

• Federal, state and/or local governments
• FedEx and UPS management
• FedEx and UPS employees
• DHL management
• DHL employees
• Labor unions representing FedEx and UPS employees
• Small package shippers

From historical data, the annual rates of return of S&P 500 stocks from 1985 to 2000 are roughly normally distributed.  The mean is 9.4%, and the standard deviation is 18.25%.  Treating the next 10 years as a simple random sample. What is the probability that the mean annual rate of return is greater than 3% (the current inflation rate)?  Round to 3 decimal places

Feeding behavior of black bream fish. In Brain and Behavior Evolution (April 2000), Zoologists conducted a study of the feeding behavior of black bream fish. The zoologists recorded the number of aggressive strikes of two black bream fish feeding at the bottom of an aquarium in the 10-minute period following the addition of food. The next table lists the weekly number of strikes and age of the fish (in days).

Week ? ? ? ? ? ? ? ? ?

Number of Strikes ?? ?? ?? ?? ?? ?? ?? ?? ??

Age of Fish (days) ??? ??? ??? ??? ??? ??? ??? ??? ???

We want to fit a straight-line model relating number of strikes(y) to age of fish (x).

a. Find ???? , ???? ??? ???? .

b. Find the least squares estimators ?̂ 0 and ?̂ 1 and give the least squares prediction equation.

c. Give a practical interpretation of the value of ?̂ 1.

d. Find ? 2 , the estimator of the variance ? 2 of the random error term ?.

e. Use the least squares model to estimate the mean number of strikes if the age of fish is 170 days.

f. List the assumptions required for the regression analysis.

g. Is there evidence that age of fish contributes information for the prediction of number of strikes? Conduct a hypothesis test using ? = 0.1.

h. Find a 97 % Confidence interval for ?1.
