The smallest number on a list is changed from 12.9 to 1.29.
a. Is it possible to determine by how much the mean changes? If so, by how much does it change?
b. Is it possible to determine by how much the median changes? If so, by how much does it change? What if the list consists of only two numbers?
c. Is it possible to determine by how much the standard deviation changes? If so, by how much does it change?
(a) It is not possible to tell by how much the mean changes, because the sample size is not known.
(b) If there are more than two numbers on the list, the median is unchanged. If there are only two numbers on the list, the median is changed, but we cannot tell by how much.
(c) It is not possible to tell by how much the standard deviation changes, both because the sample size is unknown and because the original standard deviation is unknown.
