Cooperation. The tribes that hunted together worked as a team. Men went on trips to hunt, leaving the women with the task of collecting berries and roots. Because of the fact that there wasn't any agriculture, tribes rarely came in contact with eachother, and when they did, it was easy to find somewhere else to get food.
Yes. A representative must at least be 25 years old, live in the state in which they are elected, and have been a US citizen for at least 7 years
Minimum probability is 0.05, so we have to choose n such that expected frequency corresponding to 0.05 probability should be at least 5.
Let n = 5
Expected frequency = n*p = 5 * 0.05 = 0.25 < 5
Let n = 25
Expected frequency = n*p = 25 * 0.05 = 1.25 < 5
Let n = 50
then
Expected frequency = n*p = 50* 0.05 = 2.25 < 5
Let n = 100
then
Expected frequency = n*p = 100* 0.05 = 5 = 5
Thus, for n = 100, we get expected frequency = 5,
Thus, the minimum number of times the spinner should be spun to conduct this test is 100.
