Joan conducted a study to see how common binge drinking is on her college campus. She defined “frequent binge drinking” as having five or more drinks in a row three or more times in the past two weeks. Out of 593 students who replied to her survey, 64 fit this criterion. What is the 99% confidence interval for this population proportion? Answer choices are rounded to the hundredths place.

Answers

Answer 1

Answer:

I used the function 1-proportion z-interval on the calculator, where I inputted

Successes(x) = 64Sample size(n) = 593Confidence Level(C level) = 0.99

It would result in zInterval_1Prop 64,593,0.99: stat.results, where the values are shown below as:

Lower bound (CLower) = 0.075105Upper bound (CUpper) = 0.140747test statistic (p^) = 0.107926Margin of error (ME) = 0.032821

Therefore, the 99% confidence interval would be around 0.11 ± 0.03 or range from 0.08 to 0.14.

Which expression is equivalent to x2 - 12x + 11?
O (x+11)(x + 1)
O (x - 11)(x+1)
O (x + 11)(x - 1)
o (x - 11)(x - 1)

Answers

Answer: o (x - 11)(x - 1)

Explanation:

You can find two values that has a sum of -12 and a product of 11:

[tex]x^{2} -12x+11\\(x-11)(x-1)[/tex]

Or you can use the quadratic formula:

Where:

a = 1b = -12c = 11

THIS IS AN ECONOMICS QUESTION

When economists and policy makers talk about full employment, they do not mean 100 percent employment, rather they mean reaching a certain point that still leaves a portion of the labor force unemployed. Why is this the case and what are the kinds of unemployment that exist that do not allow us to reach 100 percent employment?

Answers

Employment cannot reach 100 percent because there is always unemployment. The kinds of unemployment that do not allow 100 percent employment are frictional, structural, cyclical and seasonal unemployment
