Data were obtained in a study of the oxygen uptake of 31 middle-aged-males and females while exercising.The researchers were interested in the use of a variety of variables as predictors of Oxygen Uptake.The variables that were measured on the subjects were Age,Weight,the time taken to run a specified distance (Runtime),pulse rate at the end of the run (RunPulse),their resting pulse rate (RstPulse),and their maximum pulse rate during the run (MaxPulse).The following table from a computer analysis of the data is provided (with some entries deleted and replaced by _**). Under H₀: against H_a: to test the significance of the variable Weight,what are the values of the test statistic and the P-value of the test? A)t = 1.36 and the P-value is between 0.1 and 0.2. B)t = -1.36 and the P-value is between 0.05 and 0.1. C)t = -1.36 and the P-value is between 0.1 and 0.2. D)t = -1.36 and the P-value is greater than 0.2. E)t = 1.36;and the P-value is between 0.05 and 0.1.

Based on the table given, the test statistic for Weight is -1.36 and the P-value is between 0.1 and 0.2. This means that there is some evidence to suggest that Weight may be a predictor of Oxygen Uptake, but the evidence is not strong enough to conclude this with a high level of confidence.
