Final answer:
To find four numbers with the smallest standard deviation, select the numbers closest to the mean.
Step-by-step explanation:
To find four numbers with the smallest standard deviation, we can start by finding the mean of the data set. Since the sample size is not mentioned, let's assume it to be 4. Then, we can select the four numbers closest to the mean. For example, if the mean is 50, we can choose the numbers 48, 49, 50, and 51. This way, the standard deviation will be minimized.
