Reconsider the previous exercise on height and BMI.

a. Determine a 95% confidence interval for the population slope coefficient and interpret what this interval represents.

b. Based on your confidence interval, is there an association between height and BMI? Explain.

Data from previous exercise

The data in the file HeightBMI was obtained from a survey of statistics students. The variables recorded are the student’s heights (in inches) and their body mass index (BMI). Consider conducting an analysis to test whether the sample data provide strong evidence of an association between height and BMI using slope as the statistic. (Let height be the explanatory variable and BMI be the response.)
