Suppose you are interested in examining the relationship between a person's height and their mother's height. You randomly select 40 people for your analysis and record their heights and their mothers' heights in centimetres. You find a linear pattern in the scatterplot of the data. The table given below shows the computer output of the simple linear regression of the data to predict the height of a person based on their mother's:

Answer the next three questions based on the paragraph given above. You need not use any spreadsheet software for this purpose. The results required to answer the questions are given in the comprehension.
Question 2/3MandatoryEquation of Regression Line
Assuming the regression coefficients are estimated at a 99% confidence level, which of the following is the correct equation of the regression line?
Y = 0.7137 + 26.271X, where X represents mother's height and Y represents person's height, in centimetres
Y = 26.271 + 0.7137X, where X represents mother's height and Y represents person's height, in centimetres
Y = 0.7137 + 26.271X, where X represents person's height and Y represents mother's height, in centimetres
Y = 26.271 + 0.7137X, where X represents person's height and Y represents mother's height, in centimetres
