Examine the three samples obtained independently from three populations:

Group 1 Group 2 Group 3

14 17 17

13 16 14

12 16 15

15 18 16

16 14 16

1. State your null and alternative hypotheses
2. 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.
3. If warranted, use the Tukey-Kramer procedure to determine which populations have different means. Use an alpha level of 0.05.
4. Interpret you findings
