- What term is used to express the likelihood of an event occurring? Are there restrictions on its values? If so, what are they? If not, explain.For a Hypothesis Test, you have the following hypotheses: H0: p = 0.44 Ha: p ≠ 0.44 You have computed a Test Statistic of z = -2.42 What is the P-value?You conduct a poll of FIU students in order to determine the percentage of students (p) who agree with the statement “Hot-dogs are one of my favorite foods”. In your poll, you find that 80 out of 100 students agree. You conduct a two-sided hypothesis test where H0: p = 0.7, where p is the proportion of students whose favorite food is hot dogs. Which of the following statements are true: I. You reject the null hypothesis when α = 0.05 II. You reject the null hypothesis when α = 0.01 III. The test statistic (Z) equals Z = +1.5 Group of answer choices II only
- A claim is made that 10% of college students major in Psychology. You believe that this claimed value is too high, so you set out to conduct a hypothesis test, with the following null and alternative hypotheses, and you decide to conduct this hypothesis test using a significance (or alpha) level of 0.05. You write out the null and alternative hypotheses as follows: Ho: p = 0.10 Ha: p > 0.10 WHAT IS THE MISTAKE HERE?A claim is made that 10% of college students major in Psychology.

You will again go through the different steps that you initially learned about last week. As usual, you will need access to Table B so you can figure out the P-value in order to reach an appropriate conclusion. Are you a dog owner? It has been claimed that the proportion of households in the United States that own at least one dog is 0.58. A veterinary researcher has some reason to doubt this claim. She does not know if the true proportion of households that own a dog is larger than or smaller than 0.58; she just thinks the true proportion is different from 0.58. To test her theory, she surveys a random sample of 682 households and finds that 364 of these households report owning a dog. Use this information to conduct a hypothesis test at a significance (or alpha) level of 0.05. What will the hypotheses be? Ho: Ha: 2. What is the sample proportion?

A new version of the PREPWell course is tested on a random sample of students, and 75% of them improve their scores. The PREPWell company is conducting a hypothesis test to determine whether the new version of the course actually gives better results. The hypotheses are H0: p = 0.72 Ha: p > 0.72 where p = the proportion of all students taking the new version of the PREPWell course that will improve their SAT scores For each description below, choose from the drop-down list to indicate which decision (A, B, or C) corresponds to it.
