Question

0.3.11. Table 10.3.7 gives mean serum cholesterol levels (given in s ional Cholester top 5% or uni deciliter) by race and age for the adult population in the grams nited Sta between I Educatio n 1978 and 1980 (source: "Report of the Natioay n Program Expert Panel on Detection, Evaluation, and T ol of High Blood Cholesterol in Adults," Arch. Intern,end reamen January 1988). Test at the 0.01 level whether the true mean cholesterol levels for adi population in the United States between 1978 and 1980 are the same.

Explanation / Answer

Null hypothesis, Ho: The mean cholesterol level at all race are same

Alternative Hypothesis, H1: At least one race have different cholesterol mean among these three race.

One-way ANOVA: Cholesterol versus Race

Source DF SS MS F P
Race 2 32 16 0.04 0.960
Error 15 5962 397
Total 17 5994

S = 19.94 R-Sq = 0.54% R-Sq(adj) = 0.00%

Conclusion: The estimated p-value is 0.960. Hence, we can not reject the null hypothesis and conclude that the true mean cholesterol levels for adults population in the United States between 1978 and 1980 are the same at 0.01 level of significance.
