1. Systolic blood pressure in different age groups
The following table contains a random sample of 40 women partitioned into three groups:
Group 1: ages below 20
Group 2: ages 20 through 40
Group 3: ages over 40
The values in the table are the systolic blood pressure levels
The Hypothesis Test:
H0: u1 = u2 = u3
H1: at least one of the treatment means is different
Use the Excel Analysis ToolPak to create an Anova - Single Factor table.
Is there sufficient evidence to support the claim that women in the different age categories have different mean blood pressure levels? Give reasons for your decision.
