10 question like this .
The results of a set of measurements (in cm) are as follows: 30.6, 30.1, 30.5, 30.3, 30.5, 30.6, 30.1, 30.2, and 30.4. Calculate the sample mean and sample variance. Now suppose that these measurements were converted to inches (1 in. = 2.54 cm). What impact does this change in scale have on the sample mean and the sample variance?
