Design specifications for an arrow are that they each weigh 100 ± 10 grams. The process to make the arrows has a standard deviation of four units.


a. What is the process capability index? Assume that the process is centered with respect to specifications. Round your intermediate and final answers to 4 decimal places (e.g., .12345 would be rounded as .1235, not .1234).

Process capability index ?

b. Suppose the process average shifts to 92. Calculate the new process capability index. Round your intermediate and final answers to 4 decimal places (e.g., .12345 would be rounded as .1235, not .1234).

New process capability index ?


c. What is the probability of defective output after the process shift? Round "z" values to 2 decimal places. Round probabilities to 4 decimal places (so a probability of .12345 would be entered as .1235, not .1234 or 12.345% or something else).

Probability of defective output ?

On Franco’s first day of work as an entry-level account manager at an advertising firm, he had lunch with three women who also were entry-level account managers at the firm. During lunch, the three women made comments to Franco that they appreciated how “fit” he was and that they were glad to have a male colleague who was “easy on the eyes” and “probably great in the sack.” Franco is very conservative about sexuality and these comments made him feel very uncomfortable. Franco quit his new job immediately after lunch and filed a sexual harassment suit against the advertising firm claiming that he experienced a hostile work environment.

Using the legal rule for determining whether a hostile work environment exists, identify two reasons why Franco is unlikely to win his lawsuit.

An evolutionary psychologist hypothesizes that people will increase from the standard 24-hour sleeping and walking cycle if not exposed to the usual pattern of sunlight. To test this notion, a sample of volunteers were placed (individually) in a room in which there was no outside sunlight, no clocks, and other indications of time. They stayed in the room for a month and could turn the lights on and off as they pleased. What can the psychologist conclude with α = 0.01? The data are below.

a) What is the appropriate test statistic?

b)
Population:
---Select--- the volunteers 24-hour cycle no outside sunlight lights on lights off
Sample:
---Select--- the volunteers 24-hour cycle no outside sunlight lights on lights off

c) Compute the appropriate test statistic(s) to make a decision about H0.
(Hint: Make sure to write down the null and alternative hypotheses to help solve the problem.)
p-value =  ; Decision:  ---Select--- Reject H0 Fail to reject H0

d) compute the corresponding effect size(s) and indicate magnitude(s).
If not appropriate, input and/or select "na" below.
d =  ;   ---Select--- na trivial effect small effect medium effect large effect
r2 =  ;   ---Select--- na trivial effect small effect medium effect large effect

e) Make an interpretation based on the results.

People significantly increase from the 24-hour sleeping and walking cycle if not exposed to the usual pattern of sunlight.

People significantly decrease from the 24-hour sleeping and walking cycle if not exposed to the usual pattern of sunlight.    

People do not significantly change from the 24-hour sleeping and walking cycle if not exposed to the usual pattern of sunlight.

Write a program that calculates how many digits an integer value acquired via scanf() contains. A correctly functioning program should produce the following output, where the user entered the value 374:

Enter a number:  374
The number 374 has 3 digits


You may assume that the input integer has no more than four digits. Use if statements to test the number. For example, if the integer value entered by the user is between 0 and 9, it has one digit. If the integer value is between 10 and 99, it has two digits.

Rewrite the program without using if or switch statements. Instead use a do-while loop.

When implemented correctly, the user should be able to input any integer value (that will fit in a storage variable of type int) and its number of digits will be correctly determined without you needing to implement special logic for each possible quantity digits.

Hint:
The number of digits is very simply related to the number of times the input integer value may be divided by 10.

As part of a discussion of a proposed major restructuring, you point out that major change attempts work best when there is a “burning platform" (i.e. a great sense of urgency to change). Your boss disagrees, saying, “That’s motivating with fear. We need to change before the platform is on fire.” Take a position for or against your boss’s argument.

1.Explain in a short paragraph what a heat engine is and what it does. Make sure your explanation includes: (a) what is the purpose of a heat engine, (b) what does a heat engine need to achieve that purpose, and (c) what limits how well a heat engine can achieve that purpose ("efficiency")?

2.The idea that evaporation is a cooling process is a familiar and intuitive one. What sounds counter-intuitive at first is this claim: "Boiling is a cooling process" (but hopefully the first two videos above have convinced you of the veracity of this claim). Explain how boiling is a cooling process. Make sure your explanation refers to latent heat (or "latent heat of vaporization", to be specific). What is the key difference between evaporation and boiling?
