Sagot :
The Expected value of M is 65
The Standard error of M is 5
- The mean of the distribution of sample means is called the expected value of M.
- The standard deviation of the distribution of sample means is called the standard error of M.
Given,
The sample score, n = 9
The Standard deviation, σ = 15
Population mean, μ = 65
Then,
The Expected value of M = μ
∴ The Expected value of M = 65
The Standard error of M = σ/[tex]\sqrt{n}[/tex]
[tex]=\frac{15}{\sqrt{9} } \\\\=\frac{15}{3} \\=5[/tex]
