Answer:
The 95% confidence interval estimate of the population proportion of managers who have caught salespeople cheating on an expense report is (0.5116, 0.6484).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
In the survey on 200 managers, 58% of the managers have caught salespeople cheating on an expense report.
This means that 
95% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:

The upper limit of this interval is:

The 95% confidence interval estimate of the population proportion of managers who have caught salespeople cheating on an expense report is (0.5116, 0.6484).

Answer:
B'D' ║ BD and will be shorter than segment BD.
Step-by-step explanation:
A scale factor of 1/3 means all image segments are 1/3 the length of the preimage segments (that is, <em>shorter</em>).
Image segments not on a line through point A(1, 2) will be parallel to the preimage segments.
For this dilation, ...
segment B prime D prime will be parallel to segment BD and will be shorter than segment BD.
I did it on paper just now. Sorry for the sloppy handwriting, but you should be able to answer the two questions with the info I got. If you don't know what five number summary is, just google it.
Basically, arrange the list of numbers in order, and then find the minimum, 1st quartile, median, 3rd quartile, and maximum.
