Transcribed Image Text:6-58. A pump for a reservoir must be operated
continuously (8,760 hours per year). In the event
of a large storm, the electricity from the local utilitv's
power grid may be interrupted for an indefinite period of
time. To deal with this emergency situation, two mutually
exclusive backup diesel generators are being investigated.
One of them will be chosen for implementation. Relevant
data are provided as follows:
Generator A Generator B
Initial investment $100,000
Annual operating
$130,000
8,000 088
20AM
and maint.
9,500
Useful life, years o
15
If salvage values of both generators are negligible and
the study period is 60 years, which generator should be
chosen? The MARR is 10% per year. (6.5)

- 2. Baldur is a big fan of salaries. He collects data on wages and the length of schooling the people had from 100 employees in a large company with the aim of creating a model that can predict wages by level of education (measured in the number of years in school after primary school). The employees with the lowest level of education in Baldur's data immediately entered the labor market after compulsory school leaving, while those with the highest level of education have completed 9 years of schooling after leaving compulsory school leaving. Baldur started by drawing the data and saw that the relationship is linear. He also calculated some fish sizes that can be seen below: standard Change average deviation salary 660020 150100 Education (year from primary school diploma) 5.5 2.2 He also calculated the correlation coefficient between salary and level of education (measured in the number of years in school from primary school exam) and obtained r = 0.55. a.)

Infer the effects of increases in the minimum wage by averaging the results of other studies c. Generally find elasticity estimates for labor demand to be highly elastic d. Examine changes in the minimum wage in multiple countries I think answer is b. according to the literature below: "Research since 2007, however, has reported conflicting findings. Some studies use “meta-analysis,” averaging across a set of studies to draw conclusions. For example, Doucouliagos and Stanley (2009) report an average elasticity across studies of −0.19, consistent with earlier conclusions, but argue that the true effect is closer to zero; they suggest that the biases of authors and journal editors make it more likely that studies with negative estimates will be published. However, without strong assumptions it is impossible to rule out an…arrow_forward

(Exercise 6, Section 9.5.7) According to the Department of Motor Vehicles (DMV), the entity in charge of providing driving licenses in the United States, it is illegal to drive with a blood alcohol content of 0.08% or more if you are 21 or older. In the DMV's guidelines to determine when a person is driving under the influence, which can be found at https://www.dmv.ca.gov/portal/dmv/detail/pubs/hdbk/actions_drink, it is indicated that fewer than five percent of the population weighing 100 pounds will exceed the 0.33 alcohol level. Assume this is accurate.

- 1. Susan Sound predicts that students will learn most effectively with a constant background sound, as opposed to an unpredictable sound or no sound at all She randomly divides twenty-four students into three groups of eight. All students study a passage of text for 30 minutes. Those in group 1 study with background sound at a constant volume in the background. Those in group 2 study with noise that changes volume periodically. Those in group 3 study with no sound at all. After studying, all students take a 10 point multiple choice test over the material. Their scores follow test scoresS group 7 46 86 629 5 5 3 4 4 7 2 2 2 471 2 1 5 5 1) constant sound 2) random sound 3) no soundarrow_forwardState the type of variable in each of the following cases 1- 5.1.
