survey was conducted that asked AHC (Population 1) students and Cuesta students if they drive to school. he calculator output from a hypothesis test looks like this: -PropZTest E = 1.8 = 0.072 = 0.72 2 = 0.62 = = 0.68 . What was the claim? O AHC and Cuesta students are equally likely to drive to school O AHC students are more likely than Cuesta students to drive to school O On average, the same number of AHC students and Cuésta students drive to school OA higher number of AHC than Cuesta students drive to school . Was the test statistically significant at a = 0.05? O No, since 0.68 > 0.05 O No, since 0.072 > 0.05 O Yes, since 0.072 < 0.05 O No, since 1.8 > 0.05 E. What percentage of the AHC students drive to school? 1. What is the combined percentage of AHC and Cuesta students that drive to school?

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.
