A dot plot of times that five students studied for a test is displayed below.

Use the table to determine the mean number of hours that these five students studied. Then, complete the table.

Find and interpret the MAD for the above data set.

The same five students are preparing to take a second test. Suppose that the data were the same except that Ben studied 2.5 hours for the second test (1.5 hours more) and Emma studied only 3 hours for the second test (1.5 hours less.) Without doing any calculations, is the mean for the second test the same, higher, or lower than the mean for the first test? Explain your reasoning
