Within cоnstructiоn, understаnding the cоmpressive strength of concrete is criticаl to providing аn appropriate result for the job. As such, a study from Chung-Hua University has provided data associated with the aggregate mixtures associated with concrete, curing age, and the resulting compressive strength. Please download this dataset and provide an analysis to address the following question: A superplasticizer is being advertised as being able to improve the compressive strength of concrete but is relatively expensive. Your manager would like to understand the relationship between the use of this superplasticizer and compressive strength. Please analyze this relationship and provide a useful characterization of the results. Given the attached data set and the given scenario answer the following questions: What type of statistical analysis would you use to test this research question What would your null hypothesis (H0) and your alternative hypothesis (H1) be for the given research question? What are your independent variable(s) (IVs) and dependent variable(s) (DVs) for the given research question? Using the statistical analysis software of your choice, complete the statistical analysis to answer the given research question. Report your analysis in APA format. Be sure to include any required post hoc tests.
