Question
The mango is considered the "king of fruits" in many parts of the world. Mangoes are generally harvested at the mature green stage and ripen up during the marketing process of transport, storage, and so on. During this process, about 30% of the fruit is wasted. Because of this, the impact of harvest stage and storage conditions on the postharvest quality are of interest. In this experiment, the fruit was harvested at 80, 95, or 110 days after the fruit setting (the transition from flower to fruit) and then stored at temperatures of 20, 30, or 40 degrees centigrade. For each harvest time and storage temperature, a random sample of mangoes was selected, and the time to ripening was measured (a) What are the factors? (Select al that apply.) harvest time 20, 30, and 40 degrees centigrade the nine combinations of the different storage temperatures and harvest times time to ripening storage temperature 80, 95, and 110 days What are the treatments? (Select all that apply.) 80, 95, and 110 days 20, 30, and 40 degrees centigrade harvest time time to ripening O the nine combinations of the different storage temperatures and harvest times storage temperature What are the response variables? (Select all that apply.) 80, 95, and 110 days storage temperature the nine combinations of the different storage temperatures and harvest times 20, 30, and 40 degrees centigrade harvest time time to ripeningExplanation / Answer
1) The factors are :
The factors are the explanatory variables or the independent variables. These are the variables manipulated by the experimenter in order to check the response of the experiment.
In our case, the harvest time and the storage temperature are changed to check the final time to ripening.
Thus, Answer : e) harvest time b) storage temperature
2)
The treatments are :
Combinations of factor values are called treatments. Specific combinations or scenarios of factor variables are called treatments. In our case, we have 9 scenarios of harvest time and storage temperature : (80, 20) (80,30) (80,40) (95,20) (95,30) (95,40) (110,20) (110,30) (110,40)
These are our treatments.
Thus, Answer c) : the nine combinations of the different storage temperatures and harvest times
c) The response variables:
The response variables are the outcome of the experiement that needs to be measured in the end. In our case, we want to finally see the time to ripening of the mangoes.
Ans : f) time to ripening
Cheers!
