Reference no: EM13617844

A sample of women were divided into four age groups: Group A (20-45.9), Group B (46.0-55.9), Group C (56.0-65.9), and Group D (66 or older). Information on calcium intake was collected from each woman. Does mean calcium intake differ across the four age groups? Use alpha=.05.

1) Write out the appropriate null hypothesis and alternative hypothesis;

2) Calculate the test statistic;

3) Give your conclusion including a comparison to alpha or the critical value.
