Elliot was curious if there was a relationship between a student's gender and what superpower they'd prefer to have. He obtained data from a random sample of 206 students. Here is a summary of the data and the results from a chi-square test: Chi-square test: Superpower vs. gender Female Male Fly 19 32 Expected 27.73 23.27 Freeze time 17 23 Expected 21.75 18.25 Invisibility 23 13 Expected 19.57 16.43 Telepathy 53 26 Expected 42.95 36.05 x = 14.759, DF 3, P-value = 0.002 %3D Assume that all conditions for inference were met. At the a 0.05 significance level, what is the most appropriate conclusion to draw from this test?
Permutations and Combinations
If there are 5 dishes, they can be relished in any order at a time. In permutation, it should be in a particular order. In combination, the order does not matter. Take 3 letters a, b, and c. The possible ways of pairing any two letters are ab, bc, ac, ba, cb and ca. It is in a particular order. So, this can be called the permutation of a, b, and c. But if the order does not matter then ab is the same as ba. Similarly, bc is the same as cb and ac is the same as ca. Here the list has ab, bc, and ac alone. This can be called the combination of a, b, and c.
Counting Theory
The fundamental counting principle is a rule that is used to count the total number of possible outcomes in a given situation.
