a) State the appropriate null and alternative hypotheses.
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...

For each problem, state the null and alternative hypotheses with the appropriate notation. Then test the hypothesis at the given significance level. Lastly state your conclusion using a complete sentence. Be sure to include the p-value in your conclusion. 1. suppose it is reported that 35% of collage students smoke tobacco regularly. We are curios as to whether a higher proportion of auraria campus students smoke regularly. So we sample 150 students and find that 70 smoke. Test your hypothesis...
