Assume you are trying to determine whether hummingbirds prefer the feeder on the south side of your house or the feeder on the north side. For which of the following tests would a one-way (goodness of fit) chi-square test be appropriate? a) testing whether the mean volume of nectar consumed from the north feeder in a day differs from the south feeder
b) testing whether the number of birds that visit the north feeder in one day differs from the number that visit the south feeder
c) testing whether there is a relationship between nectar type (sugar-water vs. store bought) and feeder location (north vs. south
d) testing whether the amount of time that each bird spends at the north feeder differs from the amount of time the same bird spends at the south feeder for all birds that visit both feeders
