Suppose an automobile manufacturer designed a new engine and needs to find the best grade of gasoline for the best (highest) miles per gallon. The four grades are regular, economy, premium, and super premium. The test car made three trial runs on the test track using each of the four grades. The miles per gallon were recorded for each grade. Put these data into Minitab (STAT>ANOVA>OneWay>(Response data are in separate columns) ) and answer the following questions. Use Hmwk1Prob1Data Should the researcher print out a Tukey Comparison to see which grades have higher or lower gas mileage?

Define and defend all variables, including the dependent variable, in a single paragraph for each variable. Also, state the expectations for each independent variable. These paragraphs should be in numerical order, i.e., dependent variable, X1, then X2, etc.

Dependent Variable: Players Annual Pay
Independent Variables: Batting average, Stolen bases, Home Runs, and RBIs.

In each paragraph, the following should be addressed:
How is the variable defined in the data source?
Which unit of measurement is used?
For the independent variables: why does the variable determine Y?
What sign is expected for the independent variable's coefficient, positive or negative? Why?

The length of nylon rope from which a mountain climber is suspended has a force constant of 1.18 ✕ 10⁴ N/m.

(a)

What is the frequency (in Hz) at which he bounces, given that his mass plus the mass of his equipment is 78.0 kg?

(b)

How much would this rope stretch (in cm) to break the climber's fall if he free-falls 2.00 m before the rope runs out of slack? Hint: Use conservation of energy.

(c)

Repeat both parts of this problem in the situation where twice this length of nylon rope is used.

A sales manager is interested in determining the relationship between the amount spent on advertising and total sales. the manger collects data for the past  months and runs a regression of sales on advertising expenditures. The results wıth some missing values are presented below.

To test the significance of the regression what is the test statistic value?

Please Give All 3 answer.

Q1) A student was given a sample of crude salicylic acid to recrystallize. The initial mass of the crude acid was 131 mg. The mass after recrystallization was 121 mg. Calculate the percent recovery from recrystallization.

Q2) If 91.0 g of oxalic acid and 79.0 g of methanol react to form 89.0 g of dimethyl oxalate and water, what is the percent yield?

Q3) A student measures out exactly 0.109 g of salicylic acid and runs the experiment as dictated in the lab manual. They obtain 0.101 g of aspirin. What is the percent yield for their reaction?

A company such as Intel has a complex design and manufacturing process. This should lead Intel management to be concerned with scale of production and learning curves.

When do you think managers should be more concerned with large-scale production runs, and when do you think they should be most concerned with practices that would foster or hinder the hiring, training, and retention of key employees?

Describe a firm you think has been highly innovative. Which of the four types of innovation— radical, incremental, disruptive, or architectural— did it use? Did the firm use different types over time?

1. Real heat engines, like the gasoline engine in a car, always have some friction

between their moving parts, although lubricants keep the friction to a minimum. Would a

heat engine with completely frictionless parts be 100% efficient? Why or why not? Does the

answer depend on whether or not the engine runs on the Carnot cycle? Again, why or why

not?

2.Some critics of biological evolution claim that it violates the second law of thermo-

dynamics, since evolution involves simple life forms developing into more complex and more

highly ordered organisms. Explain why this is not a valid arguement against evolution.

Case Project 3-3: Hardware Overheating The university is having some problems with the desktop computer that runs the Intel Core Duo CPU. The computers will suddenly scramble the display screens and freeze. Because of this, the university wants to stay away from having desktops running any of the Intel CPUs. What would you recommend to address the problem? Research some of the causes of overheating hardware and suggest possible remedies. In addition, what desktop CPUs would you recommend for replacing their older hardware? Provide an explanation for your recommendation and what the university should do in the future.

bmi.txt looks like below:

25.0

17.3

23.1

37.0

What will be the output when the above code runs with the above bmi.txt file.
