Examine the three samples obtained independently from three populations:

Item Group1 Group 2 Group 3

1 14 17 17

2 13 16 14

3 12 16 15

4 15 18 16

5 16 14

6 16

1. Conduct a one-way analysis of variance on the data assuming the populations have equal variances and the populations are normally distributed. Use alpha = 0.05.
2. If warranted, use the Tukey-Kramer procedure to determine which populations have different means. Use an alpha level of 0.05.
