Quizplus · Accepted Answer

The standard error of the mean is calculated as the standard deviation divided by the square root of the sample size. Here, it is 4 / sqrt(49) = 4 / 7 = about 0.57. However, given the options, it seems there might be a mistake in the interpretation of the options or a typo in the question or options. Based on the standard calculation, none of the provided options exactly match the correct calculation result. If we proceed with the closest or a possible typo assumption, A) about 0.29 might be considered if rounding or calculation error is accounted for, but this involves assuming an error in the provided options or question details.
