A group of investigators measured calcium intake in three different treatment groups. The data are provided in Table 1. The researchers used a one-way ANOVA test to compare the difference between three treatment groups. Using alpha=0.05, what would be their conclusion?

Fail to reject the null hypothesis and conclude that the three group have the same mean of Calcium measurement. Stop there.

Fail to reject the null hypothesis and conclude that the three groups do not have the same mean of Calcium measurement. Stop there.

Reject the null hypothesis and conclude that the three groups do not have the same mean of Calcium measurement. Move on with multiple comparisons.

State whether the investigation in question is an observational study or a designed experiment. Justify your answer in each case. In the article by P. Ridker et al. titled "A Randomized Trial of Low-dose Aspirin in the Primary Prevention of Cardiovascular Disease in Women", the researchers noted that "We randomly assigned 39,876 initially healthy women 45 years of age or older to receive 100 mg of aspirin or placebo on alternate days and then monitored them for 10 years for a first major cardiovascular event (i.e., nonfatal myocardial infarction, nonfatal stroke, or death from cardiovascular causes)."
