Arguments around the legality and morality of medically assisted suicide have come to light within the last 2 decades. Opponents of such legislation state that its passing would unfairly promote an ideology that dictates one’s life-worth is based on how much of a burden they become to others. Proponents of such legislation claim that it is an individual’s right to decide when to end their own life. A medical sociologist suggests that one’s state impacts their support for such legislation. The sociologist surveys groups of 3 people from four different states to determine support for legislation based on a scale of 1 to 5 where 1 represents no support and 5 represents complete support.---ANOVA method---
California | Oregon | Montana | Missouri |
3 | 5 | 2 | 1 |
5 | 4 | 2 | 3 |
1 | 4 | 4 | 2 |
H0: Null Hypothesis: ( One’s state does not impact their support for such legislation. )
HA: Alternative Hypothesis: ( One’s state impacts their support for such legislation. ) (Claim)
From the given data, ANOVA Table is calculated as follows:
Source of Variation | Degrees of Freedom | Sum of Squares | Mean Square | F - Stat | P - Value |
Between Groups | 3 | 8.6667 | 8.6667/3=2.8889 | 2.8889/1.6667=1.7333 | 0.2373 |
Within Groups | 8 | 13.3333 | 13.3333/8=1.6667 | ||
Total | 11 | 22 |
The entries in the above ANOVA Table are calculated as follows:

SS | 8 | 0.6667 | 2.6667 | 2 |
Test Statistic F is given by:
F = 2.8888/1.6667=1.7333
By Technology,
p - value = 0.2373
Since p - value = 0.2373 is greater than = 0.05, the difference is not significant. Fail to reject null hypothesis.
Conclusion:
The data do not support the claim that one’s state impacts their
support for such legislation.
