Twenty students each conduct their own experiments to determine if plants that are insulted daily grow slower than plants that are complimented daily. After conducting their own hypothesis tests comparing the mean height of plants from the two groups, 19 students fail to reject the null hypothesis that insulted and complimented plants have the same average growth height, and one rejects the null concluding that plants do grow slower on average if insulted rather than complimented. A student claims that because one of the tests was significant, that indicates that insulting plants does indeed slow their growth compared to complimenting them. Is the student correct

Which of the following represents the range of the graph of f(x) below

How can constraints be used to model a real-world situation?

Ican interpret and represent the remainder in division calculations sensibly for the context (eg if we wont to know how many 40 seat buses will be needed to transport 170 students for on excursion, we divide 170 by 40 and realise buses and another smaller vehicle to that we need 4 transport 10 more students) solve the following questions. show your work! 11) the zoo had 420 butterflies that needed to be transported to a new enclosure. the boxes that the butterflies would be moved in only hold 80 butterflies in each. how many boxes would they need? 2 12) each classroom in the school can have exactly 25 students, if there are 345 students in the school how many full classrooms are there?
