Aresearch company polled a random sample of 799 us teens about internet use. 49% of those teens reported that they had misrepresented their age online to gain access to websites and online services. the 95% confidence interval for this number is from 45.6% to 52.5%. interpret the interval in this contexct. choose the best answer. a. there is a 95% chance that, if one were to ask all teens whether they had misrepresented their age online, 49% of them would say they have. b. there is a 95% chance that if one were to ask all the teens whether they had misrepresented their age online 49% would say they have. c. one is 95% cofident that of the 799 teens polled between 45.6% and 52.5% of them said that they had misrepresented their age online. d. one is 95% cofident that if one were to ask all teens whether they had misrepsresented their age online between 45.6% and 52.5% of them would say they have.

One is 95% confident that, if one were to ask all teens whether they had misrepresented their age online, between 45.6% and 52.5% of them would say they have.

Step-by-step explanation:

A 95% confidence interval interprets that a person is 95% sure that the true population proportion lies in it.

Given : A research company polled a random sample of 799 US teens about internet use.

49% of those teens reported that they had misrepresented their age online to gain access to websites and online services.

The 95% confidence interval for this number is from 45.6% to 52.5%.

i.e. A per son can be 95% sure that the  true proportion of all teens who admit to misrepresenting their age online is between 45.6% and 52.5%.

Correct interpretation of interval :  

One is 95% confident that, if one were to ask all teens whether they had misrepresented their age online, between 45.6% and 52.5% of them would say they have.

step-by-step explanation:

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
