Ciara, an ornithologist, has 444 bird feeders at separate locations. She wonders if birds are equally likely to visit each of th
dybincka [34]

The expected count of visits is the mean or average visits to each feeder

The expected count of visits to the third feeder is 87.5

<h3>How to determine the expected count of visit?</h3>

The table of values is given as:

Feeder                 1   2    3   4

Observed visits 80 90 92 88

In this case, the null hypothesis implies that the visits to each feeder are uniformly distributed

So, the expected count is calculated using:

Expected count =Visits/Feeders

This gives

Expected count = 350/4

Evaluate the quotient

Expected count = 87.50

Hence, the expected count of visits to the third feeder is 87.5
