Using the Framingham Heart Study dataset provided, perform the ANOVA multivariable linear

regression analysis using BMI as a continuous variable. Before conducting the analysis, be sure that allparticipants have complete data on all analysis variables. If participants are excluded due to missingdata, the numbers excluded should be reported. Then describe how each characteristic is related toBMI. Are crude and multivariable effects similar? What might explain or account for any differences?

H0 The BMI is not related to the patient characteristics in the Framingham Heart Study. (Null Hypothesis)

H1 The BMI is related to the patient characteristics in the Framingham Heart Study. (Alternative

Hypothesis)

Upload the Framingham Heart Study dataset into R Studio. (Refer to Chapters 7 (pp. 127-141) & 12 (pp.207-209) in Introductory Statistics with R or pages 111-122 in EXCEL Statistics: A Quick Guide).

Excel instructions:

Exclude participants with missing data on analysis variables (age, sex, systolic blood pressure, totalserum cholesterol, current smoker, and diabetes = cleaning the data). Conduct the simple linearregression (ANOVA) by using the Excel Regression tool in the Data Analysis Toolpak. Remember SEX is

coded 1=male and 2=female.

RStudio instructions:

Exclude participants with missing data on analysis variables (age, sex, systolic blood pressure, totalserum cholesterol, current smoker, and diabetes = cleaning the data). Conduct the simple linearregression (ANOVA) by using RStudio you will use the t.test () command and the summary () commandto get your mean and standard deviation.

Present your findings in a Word document by copying and pasting the ANOVA table into the document.

Your paper must include a title page, an introduction, a discussion where you interpret the meaning ofthe ANOVA test, and a conclusion. Your submission should be 3-4 pages to discuss and display your
