Astudy on the personality characteristics of drug dealers sampled 100 convicted drug dealers and scored them each on the wanting recognition? (wr) scale, which provides a quantitative measure of a? person's need for approval and sensitivity to social situations.? (higher scores indicate a greater need for? approval.) the sample of drug dealers had a mean wr score of 52? , with a standard deviation of 4. use this information to find an interval estimate of the mean wr score for all convicted drug dealers. use a confidence level of 90? %. interpret the result.

a.) the 90? % confidence interval for mean wr score indicates that the true mean wr score for convicted drug dealers is between and with 90% confidence.
b.) the 90? % confidence interval for mean wr score indicates that 90? % of convicted drug dealers have a wr score between and .
c.) the 90? % confidence interval for mean wr score indicates that the true mean wr score for all drug dealers is between and with 90% confidence.
d.) the 90? % confidence interval for mean wr score indicates that 90? % of all drug dealers have a wr score between and .

The 90% confidence interval for mean WR score indicates that 90% of convicted drug dealers have a WR score between 51.484 and 52.516

Step-by-step explanation:

Since the standard deviation is not known , we will be using the Student's t-distribution. So, assuming the Wanting Recognition scores are approximately Normally distributed, The 90% confidence interval is given by the interval

where

is the sample mean  

s is the sample standard deviation  

n is the sample size

is the value such that the area under the Student's t-distribution with 99 degrees of freedom (sample size -1) between is 90% or 0.9

Either by using a table or the computer, we find  

and our 90% confidence interval is

\bf [52-1.29*\frac{4}{\sqrt{100}}, 52+1.29*\frac{4}{\sqrt{100}}]=[51.484,52.516]

This 90% confidence interval for mean WR score indicates that 90% of convicted drug dealers have a WR score between 51.484 and 52.516

the central idea is that:

individuals should refuse to cooperate with institutions they believe unjust.

thoreau felt  that governments were more often agents of corruption than justice, even democracies, and that just because the majority feels a certain way does not make it just or correct in absolute terms. he uses the fact that slavery exists in our democracy to support this idea.

he goes on to say that, as a result, people should live true to their own internal laws regarding right and wrong, as a product of reflection and a moral life, rather than following every law that society imposes.
