A researcher aims to assess the associative impact of coffee consumption on death rates from heart diseases. For this objective the researcher collects data from 10 countries and intends to use linear regression. The following table shows data on average per capita coffee consumption and heart disease rate in a random sample of 10 countries. d) Using the fitted model equation, estimate the expected number of deaths if the yearly consumption is 2.9 litres. e) Estimate r using R software and interpret it. f) From linear regression fit, interpret (multiple) R^2 and state if the fitted linear model is adequate. Provide justifications to support your answer.
