= Rhino viruses typically cause common colds. In a test of the effectiveness of echinacea, 43 of the 49 subjects treated with echinacea developed rhinovirus infections. In a placebo group, 92 of the 109 subjects developed rhinovirus infections. Use a 0.05 significance level to test the claim that echinacea has an effect on rhinovirus infections. Complete parts (a) through (c) below. a. Test the claim using a hypothesis test. Consider the first sample to be the sample of subjects treated with echinacea and the second sample to be the sample of subjects treated with a placebo. What are the null and alternative hypotheses for the hypothesis test? OA. Ho: P₁ P2 H₁: P₁ = P2 O D. Ho: P₁ P2 H₁: P₁ P2 Identify the test statistic. Z= (Round to two decimal places as needed.)

Proportions On April 15th, 1912, the R.M.S. Titanic sank into the North Atlantic Ocean, resulting in the loss of more than 1,500 passengers and crew. Below is a table which summarizes the total number of passengers and the number of survivors for the crew, first-, second-, and third-class. Find the proportion of survivors by type of service (crew, first, second, third). Test the hypothesis at the 95% confidence level that the proportion of first-class survivors is the same as .50. What do you calculate for the test-statistic? What is the critical statistic? What is the conclusion of your hypothesis test? Class Passengers Survived Crew 885 212 First 325 202 Second 285 118 Third 706 178 Total 2201 710

K A poll was conducted to investigate opinions about global warming. The respondents who answered yes when asked if there is solid evidence that the earth is getting warmer were then asked to select a cause of global warming. The results are given in the accompanying data table. Use a 0.01 significance level to test the claim that the sex of the respondent is independent of the choice for the cause of global warming. Do men and women appear to agree, or is there a substantial difference? 75 01 51 16 84 31 37 90 80 Male Female Click here to view the chi-square distribution table. 00 47 Human activity Natural patterns Don't know 58 56 Ho: H₁: 321 298 Identify the null and alternative hypotheses.

Anxiety when taking math tests is a common problem. If I want to study this issue, which of the following describes the best way to find out the proportion of students who suffer from math anxiety? O Select students who have scored poorly in math classes at CCBC. Poll students as they enter campus on a randomly selected day. Talk to students randomly pulled from the list of all students. Interview students who have finals on the first day of finals week.
Thank you SO SO much!
