Assessment 3: Short Answer Questions
Weighting: 5%
Suggested due date: November 12
Related Course Objectives:
ï‚· Interpret the results of output generated from statistical computing software
ï‚· Evaluate the results of hypothesis tests
ï‚· Draw conclusions from statistical analyses
ï‚· Accept the wide range of statistical techniques available for analyzing data
ï‚· Display confidence in using and interpreting statistical analysis.
Answer the following questions and submit your response to the relevant assignment
dropbox on the course page.
A company conducts a study to see how blood pressure is influenced by an employeeâ€™s age,
weight, and job stress level classified as high stress (X2) and low stress (X3). Data recorded
on 24 employees treated as a random sample has been conducted. The tables below represent
the SPSS multiple regression output. Assume that there are no violations of assumptions.
a. Determine the multiple regression equation for the data.
b. Interpret the coefficient of determination.
c. At the 5% significance level, determine if the model is useful for predicting blood
pressure. In responding, construct and test any appropriate hypothesis.
d. At the 5% significance level, does it appear that age and weight can be removed from
the model as unnecessary? In responding, construct and test any appropriate hypothesis.
