Isolate x
So xy - 2 = k
Then
xy = k + 2
x = (k+2)/y
Answer:
b. There is a 95% chance that the true proportion of teenagers who use Mybook as their primary social network site is in the interval (0.2964, 0.9036).
Step-by-step explanation:
Hello!
In general, a 95% confidence interval for the population proportion can be interpreted as: There is a 95% chance (or confidence) that the interval will contain the true value of the proportion.
(Remember the confidence level of 95% means that if you were to make 100 intervals for the population proportion, 95 of them will contain its true value)
The estimated parameter is the population proportion of teenagers that use Mybook as their primary social network site.
With this in mind then you can say that there is a 95% probability that the interval (0.2964, 0.9036) will contain the true value of the proportion of teenagers that use Mybook as their primary social network site.
The correct answer is: b

Schanzer (Gold Fever!) raids the annals of American history once again, emerging with a feisty tall tale inspired by the Davy Crockett almanacs published in the 19th century. Assuring readers that "every single word is true, unless it is false," she spins a rollicking yarn of how Crockett (who could "whip ten times his weight in wildcats and drink the Mississippi River dry") saves the world from a disastrous collision with Halley's Comet. Deep in the woods with his pet bear, Death Hug, Crockett is bent on wooing "purty" Sally Sugartree, unaware that the president has advertised for his help to reign in the comet. Once Crockett finds out he's needed, he's off "like a high-powered hurrycane," climbing to the top of a high mountain and leaping onto the comet. In the end, a triumphant Crockett gets both the girl and his coonskin cap (to cover what's left of his comet-singed hair). Schanzer's lickety-split pace and picaresque prose are equal parts swagger and sass, and her vibrant, color-drenched paintings extend the spirited tone. Careful attention to comic detail and visual echoes of the genre's hallmark exaggeration (Crockett, for instance, has the chiseled-jaw and popping muscles of a Disney hero) frame this zesty slice of Americana admirably. Ages 6-12. (Aug.)
