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
I hope this helps!
-6 because for every value (x,y) there is another value (-x,y) so for the value (6,0) there must also be a value (-6,0). That is what the definition of y-axis symmetry is, it is also known as being an "even" function if it has this type of symmetry. Look at the graph of y=(x^2)-36 to see how this works.
Answer:
X=-27
Step-by-step explanation:
So -9x=150+93
Or -9x=243
So x=-27
Answer:4 over 6

Step-by-step explanation:
- <em>Bi-conditionals are represented by the symbol ↔ or ⇔ </em>
- <em>
p↔q means that p→q and q→p </em>
<u>Bi-conditional statement:</u>
- A rectangle is a square if and only if all four sides of the rectangle have equal length.
<u>
The associated conditional statements are:
</u>
-
a) If all sides of a rectangle are equal then it is a square.
-
b) If a rectangle is a square then all sides have equal length.
