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

So there are 152 machines. After 24 hours of operation they make 1.47x
So we know that 1.47x = 14,700,000.
Now we just divide this by 24.
14700000/24=612,500
Now thats the total, we need to divide by 152 since there are that many machines that make up that number.
612,500/152 about 4029
So your rate is 4029 per hour per machine.
The answer is 8 different combinations because you would take 3 times 5
