A medical research team wanted to perform a statistical inference procedure to see if there is a difference in the proportion of people that report headache pain relief within 30 minutes of taking either acetaminophen or ibuprofen. Volunteers that suffer from regular headaches were split into two groups: one who took acetaminophen at the onset of a headache and one group that took ibuprofen. Which of the following would be an appropriate null hypothesis for an inference test see if there is a difference between the two medications? (where A stands for acetaminophen users and I stands for ibuprofen users) A Ho: PA - Pr = 0 Ho: PA-Pr=0 C Ho: PA-Pr # 0 Ho: PA- Pr >0 |相

Based on information from a large insurance company, 66% of all damage liability claims are made by single people under the age of 25. A random sample of 51 claims showed that 43 were made by single people under the age of 25. Does this indicate that the insurance claims of single people under the age of 25 is higher than the national percent reported by the large insurance company? Give the test statistic and your conclusion.
You are a research assistant at a zoo. The question of your study is "Has the proportion of baby zebras born in zoos has changed from 10%?". Your supervisor asks that you run a hypothesis test using a significance level of 0.05. From the study, you obtain a z-score of 0.788. What type of z test is appropriate? What is the ?

A survey was conducted of visitors to the Jakarta Fair. For this reason, two groups of samples were taken. The first sample was 500 visitors for women and when they were asked 325 people said they were satisfied with the exhibition at the Jakarta Fair, while the second sample consisted of 700 visitors for gentlemen and 300 of them said they were not satisfied with the exhibition at the Jakarta Fair. the Jakarta Fair. Make a 95% confidence interval to estimate how much the difference between the two populations of visitors who are satisfied with the exhibition at the Jakarta Fair?
Postpartum depression and anxiety (PPD), is a common medical condition affecting mothers and their families after the birth of a baby. The CDC estimated that 14%14% of women who have recently given birth suffer from PPD. However, this research only reflected self-reported cases. Therefore, one group dedicated to helping women and their families with PPD believes that the true percentage of women who suffer from PPD is much higher. The group conducts a simple random sample of 101101 women who had given birth in the last year and discovers that 2020 of them report having PPD. Based on this evidence, can the group claim that the true percentage of women who have PPD is greater than 14%14%? Use a 0.020.02 level of significance. Step 2 of 3 : Compute the value of the test statistic. Round your answer to two decimal places.

Postpartum depression and anxiety (PPD), is a common medical condition affecting mothers and their families after the birth of a baby. The CDC estimated that 18% of women who have recently given birth suffer from PPD. However, this research only reflected self-reported cases. Therefore, one group dedicated to helping women and their families with PPD believes that the true percentage of women who suffer from PPD is much higher. The group conducts a simple random sample of 112 women who had given birth in the last year and discovers that 26 of them report having PPD. Based on this evidence, can the group claim that the true percentage of women who have PPD is greater than 18%? Use a 0.05 level of significance.

Random digit dialing telephone surveys used to exclude cell phone numbers. If the opinions of people who have only cell phones differ from those of people who have landline service, the poll results may not represent the entire adult population. The Pew Research Center interviewed separate random samples of cell-only and landline telephone users who were less than 30 years old. Here’s what the Pew survey found about how these people describe their political party affiliation. State the Null and Alternative Hypotheses.
Researchers from a national research organization investigated which platform (television, social media, newspaper, Internet, etc.) United States adults prefer to use to obtain their news. In 2016, of the 200 randomly selected United States adults that were surveyed, 114 selected television as their preferred platform. In 2018, of the 200 randomly selected United States adults that were surveyed, 98 selected television as their preferred platform. The conditions for inference are met. A 95 percent confidence interval for the difference in the population proportions of United States adults that use television as their preferred platform for obtaining news between 2016 and 2018 (2016 minus 2018) was found to be (-0.02, 0.18). Based on the interval, is it reasonable for the researchers to claim that there is convincing statistical evidence that the population proportion of United States adults that use television as their preferred method to obtain news differed between 2016 and 2018?

Step 3 of 3 : Draw a conclusion and interpret the decision. 1. We reject the null hypothesis and conclude that there is sufficient evidence at a 0.05 level of significance that the true percentage of women who have PPD is greater than 18%. 2.
