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

Answer:
V = 8 × 6 × 3
V = 48*3
Step-by-step explanation:
V = l*w*h
