General Objective
The study will determine the effects of green tea on serum cholesterol of hypercholesterolenemia - induced rabbits.
Specific Objectives
1.To determine the mean baseline serum cholesterol of hypercholesterolenemia – induced rabbits in 2 groups:
1.1 Experimental Group (Green Tea Group)
1.2 Positive Control (Simvastatin)
2. To determine the mean change of serum cholesterol of hypercholesterolenemia – induced rabbits in the two groups.
3. To determine if there is a significant difference in the mean change of serum cholesterol
3.1 Within groups
3.2 Between groups
And these are the computed parameters:
For Simvastatin: mean: -147.625 Variance: 281.6964 observations:8 Pearson correlation:-0.73511 For Green tea: mean:-98.125 variance:289.5536 observations:8 Additional data:
Hypothesized mean difference:0.05 df:7 t stat
df 7 t stat: -4.45165 P(T<=t)one tail: 0.001483 t Critical one-tail: 1.894578 P(t<=t)two tail: 0.002966 t Critical two-tail: 2.364623

I've taken a couple of Stats classes, but only did OK.
The Correlation analysis tool measures the relationship between two data sets that are scaled to be independent of the unit of measurement. The population correlation calculation returns the covariance of two data sets divided by the product of their standard deviations based on the following formulas.
[NOTE: The formulas did not copy/paste!--look up correlation (or other terms if you don't think this is right) in Excel's help index]
You can use the correlation analysis tool to determine whether two ranges of data move together — that is, whether large values of one set are associated with large values of the other (positive correlation), whether small values of one set are associated with large values of the other (negative correlation), or whether values in both sets are unrelated (correlation near zero).
