Medical research has shown that repeated wrist extension beyond 20 degrees increases the risk of wrist and hand injuries. Each of 24 students at a university used a proposed new computer mouse design. While using the mouse, each student's wrist extension was recorded. Data consistent with summary values given in a paper are given. Use these data to test the hypothesis that the mean wrist extension for people using this new mouse design is greater than 20 degrees. (Use

α = 0.05.

Use a statistical computer package to calculate the P-value. Round your test statistic to two decimal places and your P-value to three decimal places.)

1. State your conclusion.

Reject H₀. We have convincing evidence that the mean wrist extension for all people using the new mouse design is greater than 20 degrees.

2. Are any assumptions required in order for it to be appropriate to generalize the results of your test to the population of students from this university?

We need to assume that the 24 students used in the study are representative of all students at the university.

3. Are any assumptions required in order for it to be appropriate to generalize the results of your test to the population of all university students?

1. We need to assume that the 24 students used in the study are representative of all students who use a wireless mouse.

I am missing T and the third question

Extensions of Demand and Supply Analysis

1. Graph the accompanying demand data, and then use the midpoint formula for Ed to determine price elasticity of demand for each of the four possible $1 price changes. What can you conclude about the relationship between the slope of a curve and its elasticity? Explain in a
   nontechnical way why demand is elastic in the northwest segment of the demand curve and inelastic in the southeast segment.

2. Calculate total-revenue data from the demand schedule in question 2. Graph total revenue below your demand curve. Generalize about the relationship between price elasticity and total revenue.

3. How would the following changes in price affect total revenue? That is, would total revenue increase, decline, or remain unchanged?

1. Price falls and demand is inelastic.
2. Price rises and demand is elastic.
3. Price rises and supply is elastic.
4. Price rises and supply is inelastic.
5. Price rises and demand is inelastic.
6. Price falls and demand is elastic.
7. Price falls and demand is of unit elasticity.

4. Suppose the cross elasticity of demand for products A and B is +3.6 and for products C and D is -5.4. What can you conclude about how products A and B are related? Products C and D?

5. What is the formula for measuring the price elasticity of supply? Suppose the price of apple goes up from $20 to $22 a box. In direct response, Goldsboro Farm supplies 1200 boxes of apples instead of 1000 boxes. Compute the coefficient of price elasticity (midpoint approach) for Goldsboro’s supply/ Is its supply elastic, or is it inelastic?

Please can you specify for me which information you need?

The following data are results from a studying the effects of using four quarters or a $1 bill on keeping the money or spending it. 43 students were given the denominations.

(a) What are the two row totals?

(b) What are the two column totals?

(c) Find the probability (as a fraction and a decimal rounded to three places) of randomly selecting a student who spent the money, given that the student was given four quarters.

(d) Find the probability (as a fraction and a decimal rounded to three places) of randomly selecting a student who spent the money, given that the student was given a $1 bill.

(e) What do the preceding two results suggest?

To test whether the mean time needed to mix a batch of material is the same for machines produced by three manufacturers, the Jacobs Chemical Company obtained the following data on the time (in minutes) needed to mix the material.

a. use these data to test whether the population mean times for mixing a batch of different material differs for the three manufacturers. use .05

Compute the Values below

Calculate the value statistic

B. a the .05 level of significance, use the fisher LSD procedure to test the equality of the means for manufacturer 1 and 3

Calculate Fisher's LSD value

In a thought experiment, a cubic box of side length 0.01 mm contains three particles. One particle moves just in the x-direction, colliding elastically with the left and right walls of the cube. The second atom moves just in the y-direction, colliding elastically with the front and back walls of the cube. The third atom moves just in the z-direction, colliding elastically with the top and bottom walls of the cube. All three atoms have speed 500 m/s and mass 6.7x10-27 kg. What is the average pressure in the box?

A. 1.7 × 10-3 Pa

B. 1.7 × 10-6 Pa

C. 3.3 × 10-3 Pa

D. 5.0 × 10-6 Pa

E. 1.01 × 10-5 Pa

F. 3.10 x 10-5 Pa

A pharmaceutical company tested three formulations of a pain relief medicine for migraine headache sufferers. For the experiment, 27 volunteers were selected and 9 were randomly assigned to one of three drug formulations. The subjects were instructed to take the drug during their next migraine headache episode and to report their pain on a scale of 1 = no pain to 10 = extreme pain 30 minutes after taking the drug. a. Identify the response variable for this experiment. __________________________________(2)

b. What is the experimental unit? __________________________________(2)

Benoit Company produces three products—A, B, and C. Data concerning the three products follow (per unit):

The company estimates that it can sell 800 units of each product per month. The same raw material is used in each product. The material costs $3 per pound with a maximum of 5,000 pounds available each month.

What is the maximum contribution margin that the company can earn per month if it makes optimal use of its 5,000 pounds of materials?

Following is partial information for the income statement of Audio Solutions Company under three different inventory costing methods, assuming the use of a periodic inventory system:

Required:

1. Compute cost of goods sold under the FIFO, LIFO, and average cost inventory costing methods. (Round intermediate calculations to 2 decimal places. Round your answers to the nearest whole dollar amount.)

2. Prepare an income statement through pretax income for each method.

Sales, 328 units; unit sales price, $53; Expenses, $1,640

3. Rank the three methods in order of income taxes paid (favorable cash flow).

ABC Company produces Product X, Product Y, and Product Z. All three products require processing on specialized finishing machines. The capacity of these machines is 2,130 hours per month. ABC Company wants to determine the product mix that should be achieved to meet the high demand for each product and provide the maximum profit. Following is information about each product: Product X Product Y Product Z Selling price $ 149 $ 121 $ 35 Variable costs 104 60 27 Machine time per unit 3 hours 3 hours 1 hour Monthly demand (units) 430 280 755

Determine how the 2,130 hours of machine time should be allocated to the three products to provide the most profitable product mix. (Do not round intermediate calculations.)
