**Text and Data Analysis for Educational Context****Q3. Is the above hypothesis true? Explain by providing the P value.**Answer: Yes, if the value is greater than 0.05.**Q4. Is there a need for post-hoc tests here? Why or why not? If yes, copy, paste and interpret the result from the post-hoc test to this Word doc. If “No”, do not copy anything at all.**A table is provided below comparing data on three different diets: Carb Diet, Keto Diet, and Atkins Diet.
