He claims that the chipmunks come up to his sliding glass door of the house and scold him when the feeder is empty to get him tol it back up. 20 points) a. Provide a null hypothesis and alternative hypothesis for your neighbor's observationExplanation / Answer
2. a) From the graph : As the number of mates per female increases, the measure of reproductive output also increases although it varies a in begining and at the end but it follows a linear trend. So it can be concluded that the mates per female are directly proportional to the measure of reproductive output.
b) Dependant variable: A dependant variable is a variable which is under consideration of study or test. or anything which is measured in the experiment which can not be changed. Here " measure of reproductive output" is the dependant variable.
c) Independant varaible: A variable that is changed or controlled in an experiment to test the effects on the dependent variable. ... If the independent variable is changed, then an effect is seen in the dependent variable. Here "mates per female" is an independant variable
