A New Organic Pest Control Formula Is Being Tested on Potato

A new organic pest control formula is being tested on potato plants to see whether it can reduce the level of potato beetle infestation. The mean number of beetles per untreated plant is 5 . It is hoped that the new formula may reduce this infestation rate. State the appropriate null and alternate hypotheses.

A) $H _ { 0 } : \mu = 5 , H _ { 1 } : \mu < 5$
B) . $H _ { 0 } : \mu < 5 , H _ { 1 } : \mu = 5$
C) $H _ { 0 } : \mu < 5 , H _ { 1 } : \mu > 5$
D) $H _ { 0 } : \mu = 5 , H _ { 1 } : \mu \neq 5$
