state the null and alternative hypotheses
- A group of 19 dogs was fed Brand A of dog food for 6 weeks. Another group of 15 dogs was fed Brand B of dog food for the same 6 weeks. After 6 weeks, the skin condition of each dog was evaluated (on a numeric scale). Conduct a hypothesis test to determine if the mean skin condition of the dogs who were given Brand A was significantly different than the mean skin condition of the dogs given Brand B.

A college entrance exam company determined that a score of 22 on the mathematics portion of the exam suggests that a student is ready for college-level mathematics. To achieve this goal, the company recommends that students take a core curriculum of math courses in high school. Suppose a random sample of 150 students who completed this core set of courses results in a mean math score of 22.4 on the college entrance exam with a standard deviation of 3.8. Do...
