• a sample with a standard deviation of 24 and a sample size of 12
• a sample with a standard deviation of 12 and a sample size of 8
• a sample with a standard deviation of 14 and a sample size of 6.2
• a sample with a standard deviation of 53 and a sample size of 25

The sample with a standard deviation of 12 and a sample size of 8 will likely have the mean closest to the population mean. This is because it has a smaller standard deviation, which indicates less variability in the sample data, and a larger sample size, which allows for a more accurate estimate of the population mean.
