### EXPERIMENT:

- To determine whether a Double Stuf Oreo is
*actually* double stuffed.

### MATERIALS:

- 10 Regular Oreo Cookies
- 10 Double Stuffed Oreo Cookies
- Scissors/Blade
- Plates
- Electronic Balance

### PROCEDURE:

- Use the scissors to scrape the cream off of the Oreo's in one fluid motion. Be sure to keep single and double stuffed on separate plates.
- Mass each of the regular Oreos and set them in a pile. These Oreos will serve as the experimental control.
- Double the measured masses (from step 1) and record these values in a column labeled
*"Expected"*.
- Measure the mass of each double stuffed Oreo and record these values in a column labeled
*"Observed"*.
- Find the average and sample standard deviation of each column: Expected and Observed.
- Select an Alpha level to test (This experiment used an alpha level of .05).
- Run a statistical interference test.

### STATISTICAL DATA:

- A Two-Sample T Test will be used to determine Statistical Significance
- Null Hypothesis:
- means are equal (Oreos are properly Double Stuffed)

- Alternative Hypothesis:
- mean of expected > mean of observed (Oreos are not Double Stuffed)

- Alpha Level = 5% = .05

### RESULTS:

- T Score = 2.15697
- P Value = .02923 ~ 3%
- df = 9.28149
- pValue < alphaLevel
- There is enough evidence at Alpha Level .05 to conclude that the mean of the expected column is greater than the mean of the observed column: the null hypothesis is rejected. Therefore, we can safely conclude that Double Oreos are not actually Double Stuffed.
