Hey There!:

Sample Mean = 4.4823

SD = 0.1859

Sample Size (n) = 7

Standard Error (SE) = SD/root(n) = 0.0703

alpha (a) = 1-0.99 = 0.01

t(a/2, n-1 ) =  3.7074

Margin of Error (ME) =  t(a/2,n-1)x SE = 0.2606

99% confidence interval is given by:

Sample Mean +/- (Margin of Error)

4.4823 +/- 0.2606 = (4.222 , 4.743)

Hope this helps!

Which of these should you consider while communicating in a diverse workplace?
Ivahew [28]

Answer:

A. Culture

Explanation:

Culture is very important and is reflective of how people communicate and etc. For example, the big business setting in China differs from America, so you would want to know how to be respectful of their culture. In China, when giving and receiving business cards, you have to accept it with two hands, not one hand. Failure to do so will cause you to look rude!

I hope this helps clear things up!
