Find every possible statistic of your data. (Mean, median, mode,
standard deviation, variance, midrange, range, etc.) explain what
these statistics mean in the context of your data without
defining or using a formula. Is the statistic realistic of
the population? Is it skewed? How is it distributed? What level of
measurement is it?

1. in a test of the effectiveness of garlic for
loweringcholesterol, 45 subjects were treated with garlic in a
processed tablet form. Cholesterol levels were measured before and
after the treatment. The changes (before-after) in their levels of
LDL cholesterol (in mg/dL) have a mean of 5.1 and a standard
deviation of 15.7. Construct a 99% confidence interval estimate of
the mean net change in LDL cholesterol after the garlic treatment.
What does the confidence interval suggest about the effectiveness...
