Answer correctly and read the questions corretly, this is all one quesiton if done correclty and organized I will write a very nice review about you!

A researcher is interested in hamster wheel-running activity during the summer versus the winter. She suspects that either the hamsters will run less during the winter to conserve energy or they will run more to keep warm. She records the activity of n = 16 hamsters during June, July, and August and compares their running-wheel revolutions per hour to the activity of the same hamsters during December, January, and February. The data are collected, and the results show an average difference score of MD = 3.1 and a sum of squares of SS = 331.35. What is the value for degrees of freedom for this repeated-measures t test? O 16 oo O 37 O 15 O 34
