A teacher conducted an experiment to see if she was more likely to call on boys or girls in class. one day she recorded the numb
er of times she called on boys in class and the number of times she called on girls in class. she found that out of 30 questions she asked, she called on girls 23 times. To see if the results were typical, she ran 50 simulations and created a dot plot showing the number of times a girl was called on out of 30 questions. Were her results typical for that one day? Explain.
A) Her results were not typical. Her results were on the high end. Based on the mean of the data, she should have called on females around 16 times.
B) Her results were not typical. She should have called on females fewer than 10 times since most of the data is centered around 10.
C) Her results were typical. Most of the data on the dot plot falls between 17 and 28, and 23 lies right in the middle.
D) Cannot be determined. You can not use a simulation to see if experimental results are typical.
