Answer:
b. Ha: # of bugs with the new pesticide = # of bugs with the old pesticide
Explanation:
As seen in the question above, the new insecticide may have better results than the old insecticide that David used in his garden. To find out if this is true, David decides to spray one side of the Garden with the new insecticide and spray the other side of the garden with the old insecticide, so that he can count which of the two insecticides killed more insects and thus determine which of the products is more efficient.
To determine efficiency, David's chances are:
- # of bugs with the new pesticide < # of bugs with the old pesticide
- # of bugs with the new pesticide > # of bugs with the old pesticide
However, it is necessary to consider an alternative hypothesis, where the evaluation of the results is null. Thus, the alternative hypothesis for David's experiment is:
- # of bugs with the new pesticide = # of bugs with the old pesticide
