Question 4 of 10 • Statistical Modeling - Content Recovery - Part B
A florist wants to determine if a new additive would extend the life of cut flowers longer than the original additive. The florist randomly selects 20 carnations from the ones recently delivered by the greenhouse and randomly assigns 10 to the new additive and 10 to the original additive. After three weeks, 6 carnations placed in the new additive still looked healthy and 2 carnations placed in the original additive still looked healthy. The proportion of healthy carnations with the new additive was significantly greater than the proportion of healthy carnations with the original additive.
Answer
A
It can be concluded that the new additive caused the extended life of the cut flowers, and this inference can be applied to all carnations.
B
It can be concluded that the new additive did not cause the extended life of the cut flowers, and this inference can be applied to all carnations.
C
It can be concluded that the new additive caused the extended life of the cut flowers, and this inference can only be applied to the carnations from the greenhouse.
D
It cannot be concluded that the new additive did not cause the extended life of the cut flowers, and this inference can only be applied to the carnations from the greenhouse.
