A. 0.55
B. 0.65
C. 0.35
D. 0.45
0.65 represents the strongest correlation.
Answer: Option B.
<u>Explanation:</u>
In statistics, correlation or dependence is any measurable relationship, regardless of whether causal or not, between two arbitrary factors or bivariate information. In the broadest sense connection is any measurable affiliation, however it normally alludes to how much a couple of factors are straightly related.
For two factors, a statistical correlation is estimated by the utilization of a Correlation Coefficient, spoke to by the image (r), which is a solitary number that depicts the level of connection between two factors.
Answer:
The 1st option
Step-by-step explanation:
Line RT bisects VS at a right angle. We know that angle RTS is a right angle, so RTV is also a right angle.

Answer:
The value of ROE that will be exceeded by 78% of the firms is -1.77%.
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean
and standard deviation
the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
The mean ROE for the firms studied was 14.93% and the standard deviation was 21.74%. This means that 
What value of ROE will be exceeded by 78% of the firms?
This is the value of X when Z has a pvalue of 1-0.78 = 0.22.
This is 
So:




The value of ROE that will be exceeded by 78% of the firms is -1.77%.
