In physiology, an objective measure of aerobic fitness is how efficiently the body canabsorb and use oxygen (oxygen consumption). A physiologist, Dr. Castillejo, conducted aresearch wherein subjects participated in a predetermined exercise run of 1.5 miles.Measurements of oxygen consumption as well as several other variables such as age,gender, runtime, resting and maximum pulse rates, and weight were recorded from 50randomly selected gym members. Dr. Castillejo is interested in determining whether anyof these other variables can help predict oxygen consumption. She believes that apossible link between these factors will help her determine how to improve the health ofher gym members.Help Dr. Castillejo in developing a proposal for the improvement of her gym members' health condition. Thevariables are described below.gender- either male or femaleruntime - time to run 1.5 miles (in min)age - age of the gym member in yearsweight - weight of the gym member (in kg)oxygen consumption - measure of the ability to use oxygen in the blood stream (in ml/min)rest pulse - resting pulse rate (in bpm)maximum pulse - maximum pulse rate during the run (in bpm)Dr. Castillejo feels that maximum pulse rate during the run is a good predictor in explaining the oxygenconsumption in the blood stream. He asserts that if pulse rate at the end of the run increased, then theoxygen consumption will also increase, hence his/her heart is functioning well. Based on the Rcommander output below, check if the data on oxygen consumption and maximum pulse rate (from152bpm to 196 bpm) support Dr. Castillejo's assertion. Make sure to interpret all necessary estimates.Give the expected oxygen consumption if maximum pulse rate is 160 bpm. Also, provide a measure thatreports the adequacy of the model.R COMMANDER OUTPUT1m (formula = oxygen.consumption maximum.pulse, data = aerobic)Coefficients:Estimate Std.

Is Your Nose Getting Bigger?Next time you see an elderly man, check out his nose and ears! While most parts of the human body stop growing as we reach adulthood, studies show that noses and ears continue to grow larger throughout our lifetime. In one study1 examining noses, researchers report "Age significantly influenced all analyzed measurements:" including volume, surface area, height, and width of noses. In a test to see whether males, on average, have bigger noses than females, the study indicates that "p<0.01."Let group 1 be males and group 2 be females.1Sforza C, Grandi G, De Menezes M, Tartaglia GM, Ferrario VF, "Age- and sex-related changes in the normal human external nose", Forensic Science International, 2011 Jan 30;204(1-3):205.e1-9.
