A population with a mean of u=10 has EX=250. How many score are in the population?
To determine the number of scores in the population, we first need to understand the given information.
The mean (μ) of a population is the average value, indicating the central tendency of the data. In this case, the mean is given as u=10.
The symbol "EX" typically represents the sum of all the scores in the population (also known as the population total). In this case, it's given that EX=250.
To find the number of scores in the population (N), we need to divide the population total by the mean:
N = EX / μ
Substituting the given values, we have:
N = 250 / 10
Calculating this, we get:
N = 25
Therefore, there are 25 scores in the population.
