Ages of patients who had their tonsils removed at a hospital over the course of a year.
A) The distribution would likely be bimodal and skewed right.The procedure is much more common among young people,so most patients would be younger,perhaps 8-12 years old.Eight-year-olds would be at one mode,and twelve-year-olds would be at the other mode.The distribution would be skewed right,since it is possible to have a greater variety of ages among older people,while there is a natural left endpoint to the distribution at zero years of age.
B) The distribution would likely be unimodal and symmetric.The procedure is much more common among young people,so most patients would be younger,perhaps 8-12 years old.The distribution would be symmetric,since it is possible to have this procedure done earlier or later than the average age.
C) The distribution would likely be unimodal and skewed left.The procedure is much more common among young people,so most patients would be younger,perhaps 8-12 years old.The distribution would be skewed left,since it is possible to have a greater variety of ages among younger people

Bimodal
Describing a distribution that has two distinct peaks or modes, indicating two prevalent values.
Skewed
A term used in statistics to describe a situation where a dataset or distribution displays a lack of symmetry around the mean value.
Tonsils Removed
A medical procedure, known as a tonsillectomy, involving the surgical removal of the tonsils, typically due to recurrent infection or breathing issues.

Final Answer :
D
Explanation :
The correct choice is D because it accurately describes the distribution of ages for tonsillectomy patients. The procedure is indeed more common among younger individuals, but older people can also have their tonsils removed, albeit less frequently. This creates a distribution that is skewed right, with a concentration of younger ages and a tail extending towards older ages. The natural left endpoint at zero years of age prevents the distribution from being skewed left.
