Question

Scenario B. David sees an ad for a new pesticide that is supposed to get rid of bugs in his garden better than the brand he currently uses. He decides to test this out by using the new pesticide on one half of his garden, and the pesticide he normally uses on the other half of the garden, and then counting the number of bugs he finds on his plants. What is the null hypothesis for this study? HO: # of bugs with new pesticide = # of bugs with the old pesticide HO: # of bugs with new pesticide * # of bugs with the old pesticide

Answer 1

Answer

The correct answer is - A

The null hypothesis is something that represents the unbiased view of the researcher, which the researcher usually wants to disapprove. In the above example, Option A says that there is no significant difference in the number of bugs with new pesticide and the old pesticide. However, the researcher wants to disapprove of this by using the new pesticide on half of the garden and the old one on the other half and then noticing the result.

So, the null hypothesis for this study would be:

H0: # of bugs with new pesticide = # of bugs with the old pesticide.
