Prediction and Study of factors causing Heart Attack Video's

Introduction

This study is for the prediction of the heart attack. According to an internet article entitled “Heart attack” by MAYO CLINIC , it states that the men with the age of  45 or older and women with the age of 55 or older are more likely to have a heart attack than are younger men and women. Hence , I would like to test whether the age for men to get heart attack is 45 or older and the mean age for women to get heart attack is  55 or older . Besides that , I would like to study  how the  serum cholesterol in mg/dl ( chol ) affects the trestbps(resting blood pressure ) which is by correlation analysis. Undeniably , I would also like to study the relationship between the resting blood pressure( trestbps ) with the thalach maximum heart rate achieved ( thalach )  which is by regression analysis . On top of that , I would also like to determine whether there is a significant relationship between chest pain type ( Cp )  and  resting electrocardiographic results ( Restecg ) resting electrocardiographic results using Chi Square test of independence .

Reflection

In this project , i learn how to do the inferential analysis. I did one sample testing , correlation analysis , regression analysis  and chi square test of independence. I I get the chance to really like doing or analysis issue that i like . Its not exactly  like the question that been ask in exam or in class. This like we apply it in real life that we doing it our own. 

The biggest problem in the r programming is that i faced is the part i do the chi-square test. I hesitate for a long time whether my method is correct not . In the note , it got mention about the method used might come out warning message hence we need to merge the cells in the contingency table  once  and run again the test statistic method. After that, there will be no warning message appear. But this is not the case for me . After some consideration, i decide plan to to merge twice and  it is working. 

It is very interesting because after we analyse the variable or issues that we want to analysis , we can know more about it and determine its true or not and are there dependent and even their relationship between each other. In my view , this inferential statistic may use for business purposes. This project and this  subject  able to  prepare my self for analysis work.
