Topic

In nursing, we seldom know the true values or percentages of many illnesses or syndromes.

For example, if we were asked how many people contracted a particular strain of flu during a year then we could give estimates but not the true count.

Not everybody went to the doctor or emergency room.

Most probably did not get a test to determine the particular strain of the flu. Sometimes we just deal with estimates.

For example, in a survey done in November 2018, 43% of people in the United States had been vaccinated against the flu with 3.9% margin of error with 95% confidence (”News Scan for Dec 06, 2018”, 2018). This would allow us to create a confidence interval:lower bound = 43% – 3.9% = 39.1%upper bound = 43% + 3.9% = 46.9%so we are 95% confident that the true percentage of individuals that got vaccinated is between 39.1% and 46.9%.

Find at least two examples of confidence intervals on the internet. you can search for ”95% confidence”, ”Margin of Error”, or even ”confidence interval” to find examples.

You must proofread your paper. But do not strictly rely on your computer’s spell-checker and grammar-checker; failure to do so indicates a lack of effort on your part and you can expect your grade to suffer accordingly. Papers with numerous misspelled words and grammatical mistakes will be penalized. Read over your paper – in silence and then aloud – before handing it in and make corrections as necessary. Often it is advantageous to have a friend proofread your paper for obvious errors. Handwritten corrections are preferable to uncorrected mistakes.

Use a standard 10 to 12 point (10 to 12 characters per inch) typeface. Smaller or compressed type and papers with small margins or single-spacing are hard to read. It is better to let your essay run over the recommended number of pages than to try to compress it into fewer pages.

Likewise, large type, large margins, large indentations, triple-spacing, increased leading (space between lines), increased kerning (space between letters), and any other such attempts at “padding” to increase the length of a paper are unacceptable, wasteful of trees, and will not fool your professor.

The paper must be neatly formatted, double-spaced with a one-inch margin on the top, bottom, and sides of each page. When submitting hard copy, be sure to use white paper and print out using dark ink. If it is hard to read your essay, it will also be hard to follow your argument.
