Answer: 20 ± 11.32
Explanation: <u>Confidence</u> <u>Interval</u> (CI) is an interval of values where there is a % certainty the true mean value lies in. For example, a 95% CI means there is a 95% certainty the true mean value lies in the interval.
For the data set 2, z-value for 95% confidence interval is z = 1.96
Formula to calculate CI is
x ± 
where
x is mean
z is z-value
s is standard deviation
n is the sample number
Then:
20 ± 
20 ± 
20 ± 
20 ± 11.32
The 95% CI is 20 ± 11.32, which means there is a 95% certainty the true value is between 8.68 and 31.32.

articulates with the temporal bone to form the temporomandibular joint
Explanation:
The mandible is the lower bone of the lower jaw of the human face which consists of the ramus and the front bones and teeth.
The mandible contains an articular structure for articulation called "condyle" which help in the formation of temporomandibular joints.
The temporomandibular joint is the joint formed between the lower jaw or mandible and the temporal bone of the skull. This allows the free movement of the lower jaw.
