Answer:
(1.985, 15.815)
Step-by-step explanation:
Given that:
Sample size (n) = 20
Standard deviation (s) = 11.986
Mean (m) = 8.9
α = 99%
Using the relation :
Confidence Interval = Mean ± Error
Where ;
Error = Zcritical * standard deviation / sqrt(n)
Zcritical at 99% = 2.58
Hence,
Error = 2.58 * (11.986/sqrt(20))
Error = 2.58 * 2.6801510
Error = 6.91478958
Hence,
Lower boundary = 8.9 - 6.91478958 = 1.98521042
Upper boundary = 8.9 + 6.91478958 = 15.81478958

Hi!
Answer is Yes!
Explanation: <em>This question is super easy for me. 109 is a prime number because it has not possible to factorize it. By the other words, 109 it can only divided by the 1. Hope this helps! And thank you for posting your question at here on Brainly. And have a great day. -Charlie</em>
