Answer :
Your sample mean is likely closer to the mean width of the crab population because you took a larger sample size (51) compared to Remy's sample. The larger the sample size, the more reliable and representative the mean tends to be of the population. So, based on statistical principles, your sample mean is generally considered to be more accurate and closer to the true mean of the crab population than Remy's sample mean.
Your sample mean appears to be closer to the mean width of the crab population than Remy's sample mean. This conclusion is based on the information provided, which indicates that your sample mean is within the range of values presented (between 5 and 51), while Remy's sample mean is not explicitly stated. Without knowing Remy's sample mean, it's challenging to make a definitive comparison, but based on the data given, your sample mean seems more likely to be closer to the mean width of the crab population.
