Question

the way this is worded confuses me. Will there be one problem where male weight is x and female bmi is y. or is it two problems where x&y is male weight and bmi for the 1st problem, and x&y is female weight and bmi for problem 2?

2. Using the data set of the Health Exam Results, conduct the following of weight (WT) and Index (BMI). Number the data set from 1 to 40, and select the following individuals: . Set 1 (Malo): 1, 5, 10, 13, 15, 18, 19, 24, 29, 31, 32, 33 . Set 2 (Fomalo): 4, 9, 15, 16, 17, 22, 23, 29, 33, 37, 38, 40 Draw a scatter diagram of the sample of 12 data set ( Use graph paper and label it accordingly ) a. b. Find the correlation coefficient, r, and test its significance. c. If it is significant, find the regression line, ý- a + bx. d. Predict the Body Mass Index (BMI) of someone whose weight is x 145.7 e. Find the coefficient of determination, R2, and interpret what it means.

Answer 1

It is a simple linear regression problem with one dependent and one independent variable.

Not two problems.

What you have to do is the number assigned to males and females are given, you have to choose the weight and BMI of those males and females and create a combined data set for those values only. Now answer the questions from a. to e.

For example, select 1^st male, 5^th male, 10^th male and so on after finishing males select females in the same way. It would better if you write numbers against each male and female starting from 1 for both and then choose the numbers given in sets, it will ease your selections.
