1. How Many Licks?

2. Introduction and Research Question
How many licks would it take to get to the center of a tootsie pop?
We are using a sample size of 22 individuals.
The sample size is given a tootsie pop to lick one of the sides. All the while the individual should keep accurate counts of how many licks they lick until the center is reached. Record observations.

3. Data Collection
We recorded the amount of licks it took to reach the center for each individual.
We are confident that our sample size is a good representation of the population because we randomly chose people throughout the school, despite the fact that our sample is a Convenience Sample.

7. Description Of Stats Shape: Graph is roughly symmetric
Outliers: Individuals with licks that contained 765 and 799.

8. Hypothesis
H°: The number of licks to get to the center of a tootsie pop is equal to 254.
Hα: The number of licks to get to the center of a tootsie pop is greater or less than 254.

9. Time to Test!! Significance level: .05 Sample size: 22
We will use a one sample t test to see if the average number of licks to get to the center of a tootsie pop is truly 254.
Conditions:
Our sample comes from a SRS
Population is normal

10. Testing! t=x-µ s/n t=254-22 82/22 Our t value is 62.2
p value is:3.0086

11. Conclusion
We reject Ho because the number of licks to get to the center of a tootsie pop is not equal to 254.

12. Reflection
We could have made this better by using a larger sample size so we could get a better distribution on our graph.
