Clifford likes dogs. He wondered how much dog owners spend on their dogs in a year. He hypothesized that dog owners spend more than $1000 a year on their dogs, on average. He sampled 75 dog owners in a local community and found that these 75 dog owners spent an average $1075 on their dogs in a year. Suppose o, = $175. Assume that these 75 dog owners are representative of all dog owners in terms of amount spent on their dogs in a year. The p-value is 0.0001. What conclusion should be made? Choose the correct answer below. O A. There is not enough evidence to conclude that all dog owners spend more than $1000 on their dogs each year, on average. O B. There is strong evidence that dog owners in the study spend more than $1000 on their dogs each year, on average. O C. There is strong evidence that all dog owners spend more than $1000 on their dogs each year, on average. O D. There is strong evidence that all dog owners spend more than $1075 on their dogs each year, on average.

Concept explainers

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.
