HLT 362 Module 4 ANOVA Excel Worksheet

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 systolic blood pressure levels

The Hypothesis test:

H0: μ1=μ2=μ3
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 different age categories have different mean blood pressure levels? Give reasons for your decision.
