A farmer who grows blackberries has found his harvest to be lower than usual He suspects that some animals are eating the berries before he can pick them The farmer thinks it may be either birds landing on the bushes to feast on berries or rodents climbing the bushes from below to munch on berries He decides to first test the hypothesis that birds are eating his berries and consults with a local expert on how best to prevent the birds from eating berries He has eight fields with 10 rows of berry bushes in each field In one of his fields depicted below as viewed from above he covers half of the rows with nets that will prevent birds from landing on the bushes and he leaves the other half uncovered Over the course of 8 weeks he counts the berries harvested from each row of bushes in the test field Q3 6 The farmer s experiment was widely considered to be well designed and well implemented After 8 weeks he found no difference between groups and the berry harvest was still lower than in previous years What can he conclude about his hypothesis A Rodents are eating the berries B Birds are eating the berries C Birds are not eating the berries D The results do not address the hypothesis
