Final answer:
a)True; statistics and decision-making are grounded in the objective scientific method, which involves systematic hypothesis testing, data analysis, and interpretation.
Step-by-step explanation:
The correct answer is option a) True. The use of statistics to make decisions is indeed based upon the objective scientific method. Statistics provide a framework for collecting, analyzing, and interpreting data, which are fundamental aspects of the scientific method.
Hypothesis testing is a key component in this process, where statisticians evaluate data from samples to make inferences about populations and determine if there is sufficient evidence to reject the null hypothesis.
Moreover, a P-value of 0.03 in statistics often indicates that there is a 97% confidence that the observed difference is not due to chance, suggesting the result could be significant.
Hence, using statistics allows for an objective and systematic approach to decision-making that aligns with the scientific method's iterative process of hypothesis testing, experimentation, and refinement.
