Explanation:

9 feet
10 feet (10 ft = 10·12 in = 120 in)
130 inches
12 feet (12 ft = 12·12 in = 144 in)
145 inches

_____

Obviously, 9 < 10 < 12, so ordering by feet is easy. Then we need to figure out where the inch measurements belong.

1 foot = 12 inches, so we can figure some references to use to compare to the inch measurements.

10 feet = 10·12 in = 120 in, so 130 in is longer, by less than 1 ft.

12 feet = 12·12 in = 144 in, so 145 in is longer.

Step-by-step explanation:

An observational study is one in which the researchers monitor the effect of a risk factor on subjects without introducing interventions for the purpose of noting differences in results. An experiment is mainly a randomized control trial where subjects are assigned to groups and chosen by chance. Interventions are also introduced by the researchers so as to note the different possible results within the groups and among participants.

The above-described process incorporates an experiment and that is why the researchers introduce protein level diet as interventions. It also employs the random assignment of subjects to different groups so as to improve the accuracy of the process.
