Devise a null and alternative hypothesis, then perform a t-test using alpha =0.05 if the students in our class that are born in warm weather months are taller or shorter than those born in cold weather months. Graphically display your answer and statistically write up results. In addition, determine the effect size of this relationship and interpret. Notes: Population SDs are unknown. Assume the northern hemisphere: Warm months = April, May, June, July, August, September Cold months = October, November, December, January, February, March Use Cohen's d effect size: Cohen's d = (M2 - M1) SDpooled) where SDpooled = ((SD12 + SD22) 2) A grading rubric for Written Assignment 5 can be found in the Evaluation Rubrics folder in Moo
