Question: A crossover study was conducted to investigate whether oat bran cereal helps to lower
serum cholesterol levels in hypercholesterolemic males. Twenty three such individuals
were randomly placed on a diet that included either oat bran or com flakes: after two
weeks, their low-density lipoprotein (LDL) cholesterol levels were recorded. Each man
was then switched to the alternative diet. After a second two-week period, the LDL
cholesterol level of each individual was again recorded. The data from this study is given the following table.
N | Mean | Std | ||
Com | 23 | \[{{\bar{X}}_{com}}\] = 4.4 | \[{{s}_{com}}\] = 0.624281 | spooled = 0.683313 |
Oat | 23 | \[{{\bar{X}}_{Oat}}\]= 3.86 | \[{{s}_{Oat}}\] = 0.742345 | |
Diff | 23 | \[{{\bar{X}}_{Diff}}\]= .54 | \[{{s}_{diff}}\]= 1.028502 |
