Catalina read a report saying that the average daily high temperature in Buenos Aires a few years ago was 18.2°C. She believes that last year was warmer than this. To test her belief, she takes a simple random sample of 20 days from last year and records the daily high temperature on each chosen day. Let u represent the average daily high temperature in Buenos Aires last year. Which of the following is an appropriate set of hypotheses for Catalina's significance test? Choose 1 answer: Ho : µ = 18.2°C H:µ < 18.2°C Ho : u > 18.2°C H:µ = 18.2°C Ho : H = 18.2°C H:µ > 18.2°C Ho:u> 18.2°C H:u# 18.2°C

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.
