Answer:
The standard deviation of the sample mean is
Step-by-step explanation:
From the question we are told that
The mean is
The standard deviation is
The sample size is
Generally the standard deviation of the sample mean is mathematically represented as
substituting values
Would assume this to be: n² + 50
First term, n=1, n² + 50 = 1² + 50 = 1*1 + 50 = 1 + 50 = 51
Second term, n=2, n² + 50 = 2² + 50 = 2*2 + 50 = 4 + 50 = 54
Third term, n=3, n² + 50 = 3² + 50 = 3*3 + 50 = 9 + 50 = 59
First three terms are: 51, 54, & 59.
