Hypothesis testing

A grocery store owner claims that the mean amount spent per checkout is more than $56. A test is made of H: o' /= 56 versus H : u> 56. The null hypothesis is rejected. State the appropriate conclusion. There is enough evidence to conclude that the mean checkout amount is greater than $56. O There is not enough evidence to conclude that the mean checkout price is less than or equal to $56. There is not enough evidence to conclude that the mean checkout price is greater than $56, O There is enough evidence to conclude that the mean checkout amount is less than or equal to $56. 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 7. It is hoped that the new formula may reduce this infestation rate. State the appropriate null and alternate hypotheses. O Ho: H = 7, H1: H # 7 OH: H 7 OH: H = 7 , Hi: H
