Answer:
B. <em>There is a 90% chance that the true value of the population proportion will fall between the lower bound and the upper bound. </em>
Step-by-step explanation:
A. <em>One has 90% confidence that the sample proportion is equal to the population proportion. </em>
Confidence interval gives an interval estimate, not an equality
B. <em>There is a 90% chance that the true value of the population proportion will fall between the lower bound and the upper bound. </em>
<em>Ture. </em>
<em>C.</em><em> One has 90% confidence that the interval from the lower bound to the upper bound actually does contain the true value of the population proportion. </em>
Also true but <em>One has 90% confidence is not good interpretation. </em>
<em>D</em><em>. 90% of sample proportions will fall between the lower bound and the upper bound.</em>
<em>Lower bound and upper bound is given to estimate population proportion. </em>
Answer: |x − 82| = 3.2.
that is your answer
Step-by-step explanation:
Here is the equation represented by the situation.
M = 152 - c
You have a total number of band members. If you take away the number of concert band members, the remaining would be the number of marching band members.
The diagonals of a parallelogram bisect each other.
Therefore WC = CY.
That is,
2x + 5 = 3x + 2
Subtract 2x from each side.
5 = 3x - 2x + 2
5 = x + 2
Subtract from each side.
5 - 2 = x + 2 - 2
3 = x
Answer: x = 3
Answer:
$484.92
Step-by-step explanation:
Since you have 4 sides to the pen you will need to figure out how many yard total there is so two of your sides are 9 yards and the other two are 18 yards. now you have to add however many yards there are....
9+9=18
18+18=36
then you have to add those two numbers together
18+36=54 yards total
now you just multiply 54 by 8.98
your total amount of money you spent is $484.92
