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?
a. harvest time.
b. 20, 30, and 40 degrees centigrade.
c. the nine combinations of the different storage temperatures and harvest times.
d. time to ripening.
e. storage temperature.
f. 80, 95, and 110 days.
B) What are the treatments?
a. 80, 95, and 110 days.
b. 20, 30, and 40 degrees centigrade.
c. harvest time.
d. time to ripening.
e. the nine combinations of the different storage temperatures and harvest times.
f. storage temperature.
C) What are the response variables?
a. 80, 95, and 110 days.
b. storage temperature.
c. the nine combinations of the different storage temperatures and harvest times.
d. 20, 30, and 40 degrees centigrade.
e. harvest time.
f. time to ripening.

Answer 1

1. a and e

2. the nine combinations of the different storage temperatures and harvest times.

3. f

Explanation:

1. these factors are the explanatory variable. they are what is manipulated in order to know how the experiment would respond.

the answers are a. harvest time and e. storage temperature

2. the nine combinations of the different storage temperatures and harvest times.

3. the response variable is the variable that we are measuring. also called the dependent variable. in this case we want to know the time to which mango ripens. f. time to ripen
