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.

1 and 2 are from the same exercise.

(b) Use a straightedge to sketch the line that you think best fits the data.
(c) Find an equation for the line you sketched in part (b). (Use P, = (10, 64) and P2 = (18, 96) to form the line.)
V =
(d) Use the equation in part (c) to estimate the average test score for a person with an average quiz score of 17. (Round your answer to the nearest whole number.)
(e) The instructor adds 4 points to the average test score of each student in the class. Describe the changes in the positions of the plotted points and the change in the equation of the line.
Each point will shift four units to the right, so the best-fitting line will move four units to the right.
Each point will shift four units to the left, so the best-fitting line will move four units to the left.
O Each point will shift four units upward, so the best-fitting line will move four units upward.
O Each point will shift four units upward, so the best-fitting line will move four units downward.
O Each point will shift four units downward, so the best-fitting line will move four units downward.

A 9-year-old girl did a science fair experiment in which she tested professional touch therapists to see if they could sense her energy field. She flipped a coin to select either her right hand or her left hand, and then she asked the therapists to identify the selected hand by placing their hand just under her hand without seeing it and without touching it. A 9-year-old girl did a science fair experiment in which she tested professional touch therapists to see if they could sense her energy field. She flipped a coin to select either her right hand or her left hand, and then she asked the therapists to identify the selected hand by placing their hand just under her hand without seeing it and without touching it. Among 257 trials, the touch therapists were correct 105 times. Use a 0.01 significance level to test the claim that touch therapists use a method equivalent to random guesses. Do the results suggest that touch therapists are effective?

Suppose Aaron recently purchased an electric car. The person who sold him his new car told him that he could consistently travel 200 mi before having to recharge the car's battery. Aaron began to believe that the car traveled even farther than the company claimed, and he decided to test this hypothesis formally. Aaron drove his car only to work and he recorded the number of miles that his new car traveled before he had to recharge its battery a total of 17 separate times. The table shows the summary of his results. Assume his investigation satisfies all conditions for a one-sample t-test.

Why do zebras have stripes? One hypothesis is that stripes help keep biting flies away. Trinity wants to test this hypothesis with an experiment. She will use 15 horses as the subjects in her experiment, and assign them to 3 treatments, as follows: 5 horses will wear a fabric coat that is printed with zebra stripes, as shown above 5 horses will wear nothing 5 horses will wear a fabric coat that is printed with a solid grey colour Trinity will record a video of each horse for 1 hour. She will use the video to determine the number of biting flies that land on the horse's back. a) What types of experimental group do each of (i), (ii), and (iii) represent?
