The leader of two postpartum women's support groups is interested in the depression levels of the women in her groups. She administers the Center for Epidemiologic Studies Depression Scale (CES-D) screening test to the members of her groups. The CES-D is a 20-question self-test that measures depressive feelings and behaviors durin the previous week. The mean depression level from the screening test for the 6 women in the first group is mu_1 = 16; the mean depression level for the 10 women in the second group is mu_2 = 12. Without calculating the weighted mean for the combined group, you know that the weighted mean is: Midway between 16 and 12 Closer to 16 than to 12 Closer to 12 than to 16 Compute the weighted mean. Enter your answer rounded to one decimal place. mu = The support group leader realizes that she should also screen for alcohol abuse, so she gives the women in her two groups the Michigan Alcohol Screening Test (MAST). The MAST is a 22-question self-test focusing on the use and abuse of alcohol. The first group has a mean score of mu_1 = 18. The second group has a mean score of mu_2 = 14. Compute the weighted mean. Enter your answer rounded to one decimal place. mu =
Answers
The mean depression level for the first group is μ₁= 16.
The mean depression level for the second group is μ₂ = 12
The weighted mean is closer to 12 than to 16.
The calculated weighted mean for CES-D is 13.5
The calculated weighted mean for MAST is 17.25 ≈ 17.0 rounded to 17.
Calculating the weighted mean μ
μ= {where x1 =μ₁ and x2= μ₂ }
μ= 16×6 + 10×12/ 6+10
μ= 216/16
μ= 13.5
The first group has a mean score of μ₁= 18.
The second group has a mean score of μ₂ = 14
Calculating the weighted mean μ
{where x1 =μ₁ and x2= μ₂ ; w1= number of women in the first group and w2= number of women in the second group}
μ=
μ= 18×6 + 14×12/ 6+10
μ= 276/16
μ= 17.25≈ 17

Answer:
In this situation, most of the NASA workforce would still be composed of austronauts with jet fighter experience because they would be lured by the higher wages offered to them.
However, the difference would lie in that there would also be some austronauts without jet figther experience, who would still try to get into NASA, despite being offered lower wages.
This is a different situation to the current one, where jet fighter experience is an requirement to become a NASA austronaut, which means that those without this type of experience are barred from entering NASA, no matter how low of a wage they would be willing to take.
Final answer:
Offering higher salaries to astronauts with jet fighter experience may attract more qualified candidates with these skills, as these prepare them for the extremes of space travel. Yet, this could create salary disparity and undervalue other essential astronautical skills and experience.
Explanation:
If NASA were to revise their hiring strategy and offer higher salaries to astronauts with jet fighter experience, it might increase the number of qualified applicants with this specific type of experience. Jet fighter experience and the associated G-force training in simulators is highly valuable in the space industry as it prepares individuals for the extreme forces experienced during space travel. Furthermore, adapting to zero G (free fall or weightlessness), another specific aspect of astronaut training, could be an easier transition for those with jet fighter background.
However, this kind of strategy might create a salary disparity among astronauts, potentially leading to dissatisfaction among those without jet fighter experience. It's important to remember that there are many valuable skills and experience required in space exploration, not just those gained through jet fighter training. Higher salaries based purely on jet experience might overlook other important attributes and qualifications.

The ratios that indicate a strong capacity for a company are Low debt to equity ratio and High debt service coverage ratio.
Debt service coverage ratio is an example of a coverage ratio. It measures the solvency of a firm. A high ratio indicates greater solvency when compared with a low ratio.
Debt to equity ratio is an example of a debt ratio. A high debt to equity ratio indicates higher financial risk and weaker solvency. Thus, a lower ratio is more desirable.

Answer:
1) if the FED decides to strengthen then dollar, it will make US exports more expensive and imports cheaper. That will cause net exports to decrease, i.e. there will be less exports and more imports.
A strengthening of the US dollar helps importing companies because they will buy cheaper goods from abroad and will be able to sell them at higher domestic prices. On the other hand, exporting companies will be hit because hey loss competitiveness since their products will be more expensive.
2) If the FED decides to weaken the US dollar, the opposite will happen. Exporting companies will be favored, while importing companies will be hurt. The country will start to export more and import less.
3) Generally, the FED intervenes market through its money supply policy. When the interest rate increases or the money supply increases, the value of the US dollar will tend to lower. Even if expansionary monetary policy doesn't have an immediate impact, the expectations do matter. If people expect a devaluation of the US dollar, they will start to buy foreign currencies, which in turn will end up devaluating the US dollar. It is a self-fulfilled prophecy.
Another way the FED impacts businesses is through the interest rate. Lower interest rates will increase both domestic and foreign investment in the US.

The market equilibrium price is $5 per bushel. With the price floor of $8 per bushel, the quantity sold is 4 thousand bushels, creating a surplus.
Explanation:
The market equilibrium is determined by the intersection of demand and supply curves. At this point, the price and quantity are in balance. In this case, the equilibrium price is $5 per bushel and the equilibrium quantity is 2 thousand bushels.
With the price floor set at $8 per bushel, the price is held above the equilibrium price. This leads to a surplus, where the quantity supplied exceeds the quantity demanded. The price will remain at $8 per bushel, and the quantity sold will be 4 thousand bushels.
