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.
