Your answer should include:a) a statement of the hypothesesb) the critical value for the testc) the value of the test statisticd) a statement of conclusion In independent random samples, 262 out of 400 employed people were registered to vote, while224 out of 450 unemployed people were registered to vote. At the 5% significance level, can wesay that the percentage of employed workers who are registered to vote exceeds the percentage ofunemployed workers who are registered? Let P1 denote the population proportion of employedpeople who are registered, and let p2 denote the population proportion of unemployed who areregistered. Formulate and carry out the appropriate z-test.Your answer should include parts a), b), c), and d) as in Question #1.

A college entrance exam company determined that a score of 23 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 23.7 on the college entrance exam with a standard deviation of 3.7. Do these results suggest that students who complete the core curriculum are ready for college-level mathematics? That is, are they scoring above 23 on the math portion of the exam? Complete parts a) through d) below. a) State the appropriate null and alternative hypotheses. Fill in the correct answers below. The appropriate null and alternative hypotheses are Ho: versus H,: b) Verify that the requirements to perform the test using the t-distribution are satisfied. Check all that apply. A. The students were randomly sampled. B. The…

A dentist wondered if his appointments were distributed evenly from Monday to Friday each week. He took a random sample of 500 appointments and recorded which day of the week they were booked for. His results are: Day Appointment Frequency Monday Search 104 Chi Square Distribution Table MA Tuesday 118 Wednesday 119 Thursday 2 The dentist would like to use these results to conduct a x² goodness-of-fit test to determine if the distribution of appointments agrees with an even distribution using a 0.5% level of significance.

Identify the null and alternative hypothesis(in symbolic and sentence form), test statistic, P-value(or critical values), conclusion about the null hypothesis, and final conclusion that addresses the original claim(Don’t just say Reject the null hypothesis or fail to reject the null hypothesis). If you used the calculator, identify everything mentioned above in addition to which calculator functions and inputs for each field were used. In a clinical study of an allergy drug, 108 of the 202 subjects reported experiencing significant relief from their symptoms. At the 0.01 significance level, test the claim that more than half of all those using the drug experience relief.
Please, Identify the null hypothesis, test statistic, P-value or critical value, conclusion about the null hypothesis, and the final conclusion that addresses the original claim using the 6-step test format. the Question is below here
