You are planning a survey of starting salaries for recent computer science majors. In the latest survey by the National Association of Colleges and Employers, the average starting salary was reported to be $60,038. 5 If you assume that the standard deviation is $4300, what sample size do you need to have a margin of error equal to $500 with 95% confidence

Answers

Answer:

A sample size of 285 is needed.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

Standard deviation is $4300

This means that [tex]\sigma = 4300[/tex]

What sample size do you need to have a margin of error equal to $500 with 95% confidence?

A sample size of n is needed. n is found when M = 500. So

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]500 = 1.96\frac{4300}{\sqrt{n}}[/tex]

[tex]500\sqrt{n} = 1.96*4300[/tex]

[tex]\sqrt{n} = \frac{1.96*4300}{500}[/tex]

[tex]n = 284.1[/tex]

Rounding up

A sample size of 285 is needed.

The conference was significant because it brought together the most representative gathering of African leaders ever assembled. There were about 300 delegates representing some 65 organizations coming from 28 African countries. Of the nine independent African countries only one, Sudan was not represented.The nationalist organizations were represented by their top leadership. Therefore, whether the colonial powers like it or not, the decisions of the conference must be taken with some seriousness. The conference announced clearly that African freedom and independence are a necessity, and that the struggle to achieve independence would continue. The conferences declaration on colonialism and imperialism significantly called upon the independent African states to render maximum assistance by every means possible to the dependent peoples in their struggle. The final decision of the conference was to commend nonviolent methods but also to endorse other methods if they are deemed necessary.Presently, there is negligible Russian influence in Africa. Nevertheless, this influence will grow unless the problem of racism in the multi-racial areas of Africa is solved.
