Two procedures for sintering copper are to be compared by testing each procedure on six different types of powder. The measurement of interest is the porosity (volume percentage due to voids) of each test specimen. The results of the tests are as shown in the accompanying table.

Powder	Procedure 1	Procedure 2
1	21	23
2	27	26
3	18	21
4	22	24
5	26	25
6	19	16

Is there sufficient evidence to claim that procedure II produces higher mean porosity values? Give bounds for the p-value. What would you conclude at the α=.05 level?
