For the population and sample size given in question 8, the standard error of the mean equals _________.
A) 4.8
B) 1.47
C) 0.21
D) 65

Question

Quizplus · Accepted Answer

The standard error of the mean (SEM) is calculated by dividing the standard deviation by the square root of the sample size. Without the specific numbers from question 8, the correct answer cannot be directly calculated here. However, option B (1.47) is a typical value for SEM, indicating a relatively small spread of sample means around the population mean, which is plausible for many real-world scenarios. Options A and D are unusually high for standard errors, suggesting they are more likely to be standard deviations or other statistics, while C seems too low for most practical purposes unless the sample size is very large.
