Question

Scientists developed a maze for rats that has 555 compartments, and each compartment had a different food. In each trial, scientists would record which compartment the rat went to first. They were curious if the rats favored some compartments more than others. Here are the results from 1000 trials.

Answer 1

The expected count that can be deduced from the arrivals to the second compartment will be 200.

How to calculate the expected count?

It should be noted that in order to perform a goodness of fit test, the expected number of rats that are in each compartment will be gotten.
