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.
See attached file for more information.
The solution gives detailed steps on performing a hypothesis testing equality for three means using excel.
