Marco Torres · Accepted Answer

Final Answer : C, Explanation :  The standard error of the mean (SEM) is the standard deviation of the sample mean. It is calculated as s/√n, where s is the sample standard deviation and n is the sample size. Plugging in the given values, we get SEM = 4.15/√25 = 0.83. Therefore, the answer is choice C.
