It has been long stated that the mean temperature of humans is 98.6 degrees Faranheit. However, two researchers currently involved in the subject though that the mean temperature of humans is less than 98.6 degrees. They measured the temperatures of 44 healthy adults 1 to 4times daily for 3 days, obtaining 200 measurements. The sample data resulted in a sample mean of 98.3 and a sample standard deviation of 1.1 degrees. Use the P-value approach to conduct a hypothesis test to judge whether the mean temperature of humansis less than 98.6 degrees at the a= 0.01 level of significance.
State the hypothesis.
Find the test statistic.

Westerville Company reported the following results from last year’s operations:

Sales $ 1,500,000
Variable expenses 690,000
Contribution margin 810,000
Fixed expenses 435,000
Net operating income $ 375,000
Average operating assets $ 1,250,000

At the beginning of this year, the company has a $350,000 investment opportunity with the following cost and revenue characteristics:

Sales $ 420,000
Contribution margin ratio 70 % of sales
Fixed expenses $ 252,000

The company’s minimum required rate of return is 10%.

Suppose we are thinking about replacing an old computer with a new one. The old one cost us $1,210,000; the new one will cost $1,470,000. The new machine will be depreciated straight-line to zero over its five-year life. It will probably be worth about $210,000 after five years.

The old computer is being depreciated at a rate of $242,000 per year. It will be completely written off in three years. If we don’t replace it now, we will have to replace it in two years. We can sell it now for $330,000; in two years, it will probably be worth $111,000. The new machine will save us $281,000 per year in operating costs. The tax rate is 40 percent, and the discount rate is 11 percent.

a.

Calculate the EAC for the old computer and the new computer.

New Computer EAC:

Old Computer EAC:

b.

What is the NPV of the decision to replace the computer now?

A “Remski Deck” is a deck of cards consisting of nine cards in each of 10 denominations, A, 2, 3, 4, 5, 6, 7, 8, 9 and 10. In each denomination there are three cards in each of the three suits Harps: (H), Scythes (S) and Roses (R). So there are three different 2H, three different 10S, etc. for a total of 90 cards. A “hand” of eight cards is dealt. In a hand, the order the cards are dealt do not matter, and the cards of the same denomination and suit are indistinguishable. A hand is a “pair” if there are two cards of the same denomination and none of the other cards in the hand have the same denomination as the pair or each other. A “straight” consists of 8 cards in numerical order. A “flush” consists of all 8 cards from the same suit. Answer the questions below leaving your answers as combinatorial expressions. (a) How many hands contain exactly one pair? (It does not matter if the hand is also a straight or flush). (b) How many hands are straights? (It does not matter if the hand is a flush or a pair). (c) How many hands are flushes but not straights? (The hand can contain pairs).

You have been asked for your advice in selecting a portfolio of assets and have been given the following data:

Expected return

Year Asset A Assest B Assest C

2019 12% 16% 12%

2020 14% 14% 14%

2021 16% 12% 16%

You have been told that you can create two portfolios—one consisting of assets A and B and the other consisting of assets A and C—by investing equal proportions (50%) in each of the two component assets.

a. What is the expected return for each asset over the 3-year period?

b. What is the standard deviation for each asset’s return?

c. What is the expected return for each of the two portfolios?

d. How would you characterize the correlations of returns of the two assets making up each of the two portfolios identified in part c?

e. What is the standard deviation for each portfolio?

f. Which portfolio do you recommend? Why?

1. Two streams (Brimer and Standifer creeks) located in the same watershed are similar in size/shape and most habitat conditions (e.g., temperature, dissolved oxygen, channel substrate); however, they exhibit different pH values. Brimer Creek has a mean pH of 6.1, whereas Standifer Creek has a pH of 5.6. A stream ecologist wishes to determine whether the pH has an influence on the local distributions of benthic macroinvertebrates (annelids, crustaceans, insects) in the two streams. Two study sites were established (one in each stream) that are in close proximity to each other (~50 m apart, separated by a ridge) and located near the mouths of their respective streams. Benthic invertebrates were collected at the two sites using a standardized kick-sampling technique (equal sampling times and areas). Invertebrates were counted in samples from the two sites. The data are summarized below. Number of invertebrates per sample: Brimer Creek, n = 1373 individuals Standifer Creek, n = 955 individuals Perform a G-test for goodness of fit (α = 0.05) to test the ecologist’s hypothesis.
