Determine μoverbar(x)and σoverbar(x) from the given parameters of the population and the sample size. Round the answer to the nearest thousandth where appropriate. μ = 25, σ = 12, n = 16
Answers
Answer:
μoverbar(x) = 25
σoverbar(x) = 3
Explanation:
Given That :
Population mean, μ = 25,
Population standard deviation, σ = 12,
Sample size, n = 16
The sampling distribution is approximately normal from the central. Limit theorem and hence, μoverbar(x) = μ = 25
σoverbar(x) is the standard error and is obtained thus :
σoverbar(x) = σ / sqrt(n)
σoverbar(x) = 12 / sqrt(16) = 12 /4 = 3
Following are the calculation to the [tex]\bold{\mu_{\bar{x}} \ and\ \sigma_{\bar{x}}}[/tex]:
Given:
[tex]\mu = 25\\\\\sigma = 12\\\\ n = 16[/tex]
To find:
[tex]\bold{\mu_{\bar{x}} \ and\ \sigma_{\bar{x}}}[/tex]:=?
Solution:
[tex]\mu=[/tex] population mean [tex]\sigma =[/tex]the population's standard deviation [tex]n=[/tex] size of the sample [tex]\mu_{\bar{x}} =[/tex] the average of a large number of samples of size 16 whose individual means are [tex]\bar{x}[/tex] [tex]\mu_{\bar{x}} = \mu = 25\\\\[/tex][tex]\sigma_{\bar{x}}[/tex]= the average standard deviation of all the different samples drawn from the population.[tex]\to \sigma_{\bar{x}} = \frac{\sigma }{\sqrt{n}} = \frac{12}{\sqrt{16}} = \frac{12}{4}= 3[/tex]
Therefore, the final value of [tex]\bold{\mu_{\bar{x}} \ and\ \sigma_{\bar{x}}}[/tex] is "25 and 3".

By taking the quotients between the percentages, we will get:
1) 0.7702)0.2703) 0.0124) 0.5225) 0.478How to get the probabilities?
1) The probability of not getting an orange one is equal to the quotient between the percentage of not orange ones, and 100%.
We know that 23% are orange, then 100% - 23% = 77% are not orange, so the probability is:
P = 77%/100% = 0.770
2) 12% are red, 15% are green, so 27% are either red or green, the probability is:
P = 27%/100% = 0.270
3) To get 3 blues we can estimate the probability as:
P = (23%/100%)^3 = 0.23^3 = 0.012
But this would be incorrect, as we draw blue peanuts, the probability of drawing another is reduced (because now there are less on the package).
4) Same procedure as before, 15% are green, so 85% are not green, so to draw 4 non-green ones the probability is:
P = (85%/100%)^4 = 0.522
5) The probability of getting at least one green in 4 daws is 1 less what we got above.
P = 1 - 0.522 = 0.478

Generativity vs Stagnation
Answers
During this time, adults strive to create or nurture things that will outlast them; often by parenting children or contributing to positive changes that benefit other people. Contributing to society and doing things to benefit future generations are important needs at the generativity versus stagnation stage of development.
What Are Generativity and Stagnation?
Generativity refers to "making your mark" on the world by caring for others as well as creating and accomplishing things that make the world a better place. Key characteristics of generativity include:
Making commitments to other people
Developing relationships with family
Mentoring others
Contributing to the next generation.
As you might imagine, these sorts of things are frequently realized through having and raising children. Those who are successful during this phase will feel that they are contributing to the world by being active in their home and community.
Stagnation refers to the failure to find a way to contribute. These individuals may feel disconnected or uninvolved with their community and with society as a whole. Some characteristics of stagnation include:
Being self-centered
Failing to get involved with others
Not taking an interest in productivity
No efforts to improve the self
Placing one's concerns over above all else
Those who fail to attain this skill will feel unproductive and uninvolved in the world.

Answer:
Numerous studies have shown that caffeine is toxic to a variety of wildlife at high concentrations. The effects are less clear in cases of continual exposure at low levels like those documented in nature by Granek and Nagoda because little research has been done in this area. Studies involving the use of caffeine on plants have shown that, initially, cell growth rates are stable but soon the caffeine begins to kill or distort these cells, resulting in a dead or stunted plant.

Base your answer to the following question on the following maps and your knowledge of civics: Two maps are shown depicting unemployment in the United States. One map shows rates in 2007 and the second shows unemployment rates in 2009. A map key shows that gray represents 16.5 percent or greater unemployment, purple represents 13.1-16.4 percent unemployment, dark red represents 11.0 - 13.0 percent unemployment, bright red represents 8.9-10.9 percent unemployment, dark orange represents 7.1-8.8 percent unemployment, light orange represents 5.5-7.0 percent unemployment, bright yellow represents 4.1-5.4 percent unemployment, white represents 4.0 percent or lower unemployment. The 2007 map shows a large portion of the Midwest in white. The west coast is largely yellow and orange. The east coast and central part of the U.S. are also largely yellow and orange. There are a few scattered splotches of red, and a very few purple and gray areas. The 2009 map is dramatically different. It shows a large area of the central U.S. and most of the west coast in red, dark red, purple and gray. There are now very few white areas on the entirety of the map. The Midwest still has the lowest unemployment, but much of it is now yellow and orange. Public Domain It has been argued that elected officials are less likely to be reelected if the unemployment rate increases during their term in office. If this is true, which statement is supported by the maps above? Candidates running for reelection in 2009 were less likely to win their races. Candidates running for office in 2009 were highly unlikely to be impacted by unemployment rates. Candidates running for office in 2007 were highly likely to be impacted by unemployment rates. Candidates running for reelection in 2009 were more likely to win their races.
