Hi, need help with this question

A researcher is interested in studying how age (in years) associates with resting heart rate (beats per minutes) of adult men. He recruited 35 adult men and recorded their age and measured the resting heart rate (RHR). The researcher is specially interested in understanding whether the resting heart rate of older men is higher.

1. Identify the response and the predictor variables in the study
2. Obtain the least squares regression line of RHR on age.
3. Interpret the regression coefficients in the context of the problem.
4. Using the MINITAB output of your choice, test whether the resting heart rate increases with age. Clearly state your null and alternative hypothesis, find the p value for the test and state your final conclusion.

Below MINITAB outputs are provided to you.
