3) independent samples
Step-by-step explanation:
1) couples were taken and their behaviors matched
2) only one sample was used
3) two different samples were used and their average compared.
60 degrees or C. Since the missing angle is the opposite of the 120 degree angle, 180 degrees minus(since that is the amount of degrees in a straight line, and a circle contains 360 degrees) the other angle gives you your answer.
The median of the data would be (20+25)/2, which is 45/2 = 22.5.
The first quartile (Q1), the middle number between the smallest number and the median of the data set, is 9.
The second quartile (Q2) is the median of the data. (22.5)
The third quartile (Q3) the middle value between the median and the highest value of the data, is 35.
Hope this helped!
