An agricultural scientist is investigating the efficacy of a new bio-pesticide on a common crop pest. They want to test whether the proportion of pests eliminated within 24 hours of application is greater than the historical standard of 0.70. The scientist applies the pesticide to a random sample of 120 pests and records whether each pest is eliminated. They decide to use a Binomial hypothesis test to analyse their findings.
Apart from referencing that the outcome for each pest is binary (eliminated vs not eliminated), state two reasons why a Binomial hypothesis test is appropriate for this investigation.
