The three components that are most important for establishing credibility are competence, caring, and Character 
Credibility includes objective and subjective elements of the credibility of a source or message. Authenticity goes back to Aristotle's rhetorical theory. Aristotle defines rhetoric as the ability to see potentially persuasive things in any situation. He classified the means of persuasion into three categories: ethos (reliability of sources), pathos (emotional or motivational appeals), and logos (logic used to support claims). Affect the recipient of the message. According to Aristotle, the term "ethos" deals with the personality of the speaker.
The speaker's intention is to appear believable. In fact, the speaker's psyche is the rhetorical strategy employed by the speaker with the aim of "instilling confidence in the audience." Credibility has two key components, he said, credibility and expertise, both of which have objective and subjective components. Reliability is based on subjective factors, but can also include objective measures such as perceived reliability.

Mike brought 100 shares costing $53 each.
Total costs of shares= 100*53
=$5300
He got dividends of $1.45 per share. A dividend is money that is earnt back from a share.
Total dividend amount = 1.45*100
=$145
I'm assuming that Mike sold his shares at the end of the year. He sells for $60 each.
Total sales amount=60*100
=$6000
The rate of return in this instance can be defined as the amount of money made back from a share. 
Rate of return= total earnings/ costs
Total costs= $5300
Total earnings=$6145
6145/5300=1.1594
=15.9%
Hope this helps! :)
        
             
        
        
        
 The correct answer is - allows managers to use the normal distribution as the basis for building some control charts.
<u>Explanation:</u>
It is the theorem that allows inference from a random sample. It says that:
•	The sample mean will likely be towards the population mean within a margin of error
•	The margin of error is a multiple of the standard error, which is the standard deviation divided by the square root of the sample size. The multiple is determined by the degree of statistical confidence you’re looking for, and the normal deviate corresponding to that — 1.65 for 90% confidence, 1.96 for 95% confidence, etc.
