A population of N = 6 scores has Σ X = 30. What is the population mean?Group of answer choices53018015
Question
Solution 1
To find the population mean, you need to divide the sum of the scores (Σ X) by the number of scores (N).
Given: Σ X = 30 N = 6
Population mean (μ) = Σ X / N μ = 30 / 6 μ = 5
So, the population mean is 5. Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study problem. Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve
