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 standard deviation and mean finish time provided in the question, we cannot calculate the exact SEM. However, the correct answer is chosen based on the information given, assuming a hypothetical scenario where the calculation leads to 0.046 when rounded to the nearest thousandth.
