Answer:
The formulas are functionally the same, but 'n' (the sample size) is used instead of 'N' (the population size).
Step-by-step explanation:
The sample mean is the average value for a set of observations which is derived from a population. While the population mean is the average value for the entire set of observation belonging to a particular study of interest.
The set of observation belonging to a population is denoted by 'N' ; while the sample size is denoted as 'n' :
The mean formula is written thus :
Population mean = Σx / N
Sample mean = Σx / n
Where, x = set of values.

Answer:
Option B
7/64
Step-by-step explanation:
Since the she bought 7/8 of a pound of grapes, the amount of grapes that Timothy's mum will be sharing is only 7/8 of a pound
Total number of kids = 6
To get the amount that each kid will get, we will have to divide 7/8 by 6
Hence we have
Hence, each child will get 7/64 of a pound of grapes, if the grapes are shared equally.
