Answer:
• Random sampling [ Probability and statistics method ]
Step-by-step explanation:
• This method is easier and saves time.
By probability, a person whose height is to be recorded will be chosen randomly. This will be done on approximately 40% members.
By statistical step, we'll feed results into distribution table. Then we'll find the mean height.
• f of n is product of frequency and respective height bracket
• n is the number of samples.
"Double h" means h^2 (h squared) or h times h.
Then, we multiply 4 by the result:
4h²
Remember, we always put a number before a variable.
h²4 is wrong and confusing.
