You, as a researcher, were asked to investigate differences in fruit and vegetable consumption among males and females in your city. Suggest three different probabilistic sampling methods to design this study. The sampling frame must be also stated. Explain your answers.

Part 2: Write a research question (that is, a research project) that you are interested in conducting. Write the main objective of the research project together with a null and alternative hypothesis. Suggest a probabilistic and a non-probabilistic sampling method for your study population. List your alpha significance level, and suggest at least 2 ways to lower the chances of making type 1 error.
