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!

<h3><u>
Explanation:</u></h3>
Perceptual barriers are the subconscious barriers that we build because of the thoughts that we hold of specific people, circumstances or situations throughout us. Perceptual barriers to communication are likewise challenging to understand and decode correctly because they take spot mentally.
