An inequality for a number exceeds 9

1 answer:

4 0

We are asked to write an inequality that would represent a number exceeds 9. In the problem, we need to assign "n" variable to represent the number (any number) and we need to ">" symbol to represent "greater than" or "exceed". Thus, the inequality can be represented as:
n > 9

The answer is n > 9 and this would represent the phrase "a number that exceeds 9".

A researcher would like to estimate p, the proportion of U.S. adults who support recognizing civil unions between gay or lesbian

SOVA2 [1]

Answer:

(b) 4,445

Step-by-step explanation:

If the researcher would like to be 95% sure that the obtained sample proportion would be within 1.5% of p (the proportion in the entire population of U.S. adults), what sample size should be used?

Given a=0.05, |Z(0.025)|=1.96 (check standard normal table)

So n=(Z/E)^2*p*(1-p)

=(1.96/0.015)^2*0.5*0.5

=4268.444

Take n=4269

Answer:(b) 4,445
