A population has a standard deviation of 20.2. What is the standard error of the sampling distribution of the sample size is 169?
1.44
1.84
1.68
1.55
The standard error of the sampling distribution can be calculated using the formula: standard error = standard deviation / sqrt(sample size)
In this case, the standard deviation is 20.2 and the sample size is 169.
Standard error = 20.2 / sqrt(169) = 20.2 / 13 = 1.55
Therefore, the standard error of the sampling distribution is 1.55.
The correct answer is 1.55.
