This data is for questions 1- 3 of your assignment. This data set corresponds to patient records. The dependent variable here is Risk of stroke of an individual. The independent variables are Age, Blood Pressure and if an individual is Smoker or not. The questions are also listed here below:

1. Obtain the regression equation for predicting Risk based on the given factors:age,blood pressure and smoker. Enter the value of the coefficient of Age (round up to 2decimal places).

2. It is known that Oliver is a smoker,has 230 blood pressureand his risk is known to be 1.What is Oliver's age?

3. Reply with Yes or No to the following statement.

From your regression analysis output you can conclude that:

Smoking is a significant factor in the risk of stroke at 0.05 level of significance sincep value for the variable Smoker is 0.01 which is less than 0.05. Hence
