Answer:
8
Step-by-step explanation:
Recall the formula for the population mean of a data set:
[tex]\mu=\frac{\sum x}{N}[/tex]
We already know that μ is 6 and the sum is 48. Substitute:
[tex]6=\frac{48}{N}[/tex]
Divide both sides by 48:
[tex]\frac{1}{8}=\frac{1}{N}[/tex]
Reciprocal of both sides:
[tex]N=8[/tex]
Thus, there are 8 scores in the population size.
And we're done!
Answer:
8
Step-by-step explanation:
mean=(total)/(number of terms )
number of terms=total/mean=∑x/μ=48/6=8
