A population with a mean of µ = 6 has ΣX = 42.How many scores are in the population?​
A)​N = 6/42 = 1/7
B)​N = 42/6 = 7
C)​N=42
D)​N = 6*42 = 252

Quizplus · Accepted Answer

The formula for the mean is µ = ΣX/N. Rearranging this formula gives N = ΣX/µ. Plugging in the given values, we get N = 42/6 = 7. Therefore, there are 7 scores in the population.
