Based on the NYC Department of Health Community Health Survey in 2010, a 95% confidence interval for the proportion of New Yorkers who were tested for HIV in the past 12 months is (29.9%, 32.9%). If the population size is 6 million in 2010, with 95% confidence, we know that at least how many New Yorkers were tested for HIV within the past 12 months?

With 95% confidence, at least 1,794,000 were tested for HIV within the past 12 months

Step-by-step explanation:

The lower bound of the confidence interval is 29.9%.

So, with 95% confidence, we know that at least 29.9% of the New York population tested for HIV.

Out of 6 million, that is:

0.299*6000000 = 1,794,000

With 95% confidence, at least 1,794,000 were tested for HIV within the past 12 months

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
