Consider a 95 percent confidence interval constructed for the difference between two population
proportions PR and Ps. The interval for PR - Ps is given as (-0.05, 0.15). Which of the following is an
appropriate interpretation of the confidence level?
In repeated random sampling with the same sample size, êr - Ộs will be contained in
the interval approximately 95 percent of the time.
In repeated random sampling with the same sample size, PR will be contained in the
interval approximately 95 percent of the time.
In repeated random sampling with the same sample size, Ôr will be contained in the
interval approximately 95 percent of the time.
The probability is 0.95 that the difference in the sample proportions PR - Ổs is between
-0.05 and 0.15
In repeated random sampling with the same sample size, approximately 95 percent of the
intervals will capture the difference in population proportions, PR - Ps.

#17. The height, H metres, of a certain species of Fir
tree can be estimated from the formula.
h= 35d , where d metres is the diameter at the
base. use the formula to determine the approximate
height of a fir tree with base diameter 3.2 m.
Answers
Answer:
The approximated height of the tree is of 112 meters.
Step-by-step explanation:
The height of a tree with a base diameter of d meters is approximated by the following formula:
[tex]h = 35d[/tex]
In this question:
Base diameter of 3.2m, so [tex]d = 3.2[/tex], and the height is in meters.
[tex]h = 35d = 35(3.2) = 112[/tex]
The approximated height of the tree is of 112 meters.

Answer:
(c) No, it is not a rectangle because the diagonals are not congruent
Step-by-step explanation:
The diagonals of a rectangle bisect each other and are the same length. The lengths of the diagonals of this figure are ...
AC = √((8-0)² +(6-2)²) = √(64+16) = 4√5
BD = √((5-3)² +(2-6)²) = √(4 +16) = 2√5
The diagonals are different lengths, so the parallelogram is not a rectangle. This is described correctly in choice C:
No, it is not a rectangle because the diagonals are not congruent.
_____
The lengths are found using the distance formula:
d = √((x2 -x1)² +(y2 -y1)²)
It's C, the diagonals are not congruent (they aren't equal) and with rectangles they always have to be.
