Are you in favor of the Death Penalty of someone convicted of murder? Cameron Questereit A.Z. Kyzylov Taylour Shaw

Systematic Sample Point of estimate For:.6 Against:.4 We are 95% confident that the amount of People for the death penalty is between (.425,.775) We are 95% confident that the amount of People against the death penalty is between (.225,.575)

Convenience Sample Point of estimate For:.776 Against:.223 We are 95% confident that the amount of People for the death penalty is between (.615,.917) We are 95% confident that the amount of People against the death penalty is between (.072,.374)

Stratified Sample We are 95% confident that the amount of Freshman’s for the death penalty is between (.499,.814) We are 95% confident that the amount of Freshman’s against the death penalty is between (.186,.5) We are 95% confident that the amount of Sophomore’s for the death penalty is between (.545,.721) We are 95% confident that the amount of Sophomore’s against the death penalty is between (.279,.455) We are 95% confident that the amount of Junior’s for the death penalty is between (.597,.802) We are 95% confident that the amount of Junior’s against the death penalty is between (.198,.402) We are 95% confident that the amount of Senior’s for the death penalty is between (.806, 1) We are 95% confident that the amount of Senior’s against the death penalty is between (0,.194) Point of Estimate FreshmanSophomoresJuniorSenior For: Against:

Simple Random Sample Point of estimate For:.733 Against:.267 We are 95% confident that the amount of People for the death penalty is between (.575,.891) We are 95% confident that the amount of People against the death penalty is between (.109,.425)

Statistically Different Most of the data we gathered with our methods match when comparing the confidence intervals with the National poll we found online. The only data that did match up was the senior’s of the stratified sample. There was a statistical difference between their answers and the national poll. Overall our results were not statistically different from the national poll.

Yogurt vs. Light Yogurt We measured sugar levels between regular yogurt and its dietary supplement. Point of Estimate Regular: 5.15 Light:.81 We are 90% confident that the amount of fat in the regular brands of yogurt is (.831, 9.459) grams We are 90 % confident that the amount of fat in the nonfat brands of yogurts is between (0, 1.663) grams

Statistically Significant There is a statistically significant difference between nonfat and regular yogurts We learned that nonfat yogurts still contain a little amount of fat, where regular yogurts contain a lot more. We also observed that the amount of fat and sugar was opposite of each other. Where if there was more fat there would be less sugar

Conclusions We conclude that our results we used on the national poll question does match with the source we used. Regular yogurt does contain more fat than its dietary supplement. Also that when yogurt has less fat it usually means it will have more sugar.
