Design an imaginary study that has an experimental or quasi-experimental design that used or would use t-tests or ANOVAs in the data analysis. What is the null hypothesis?

Describe the statistical method used in the analysis of data, either t-tests or ANOVAs. Discuss why your choice was appropriate for your study.
