Suppose 226 subjects are treated with a drug that is used to treat pain and 54 of them developed nausea. Use a 0.10 significance level to test the claim that more than 20% of users develop nausea. Identify the null and alternative hypotheses for this test. Choose the correct answer below. O A. Ho: p=0.20 H₁: p0.20 H₁: p=0.20 C. Ho: p=0.20 H₁: p>0.20 D. Ho: p=0.20 H₁: p=0.20 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is (Round to two decimal places as needed.) Identify the P-value for this hypothesis test. The P-value for this hypothesis test is (Round to three decimal places as needed.) Identify the conclusion for this hypothesis test. O A. Fail to reject Ho. There is not sufficient evidence to warrant support of the claim that more than 20% of users develop nausea. B. Reject Ho.

One study claimed that 86 % of college students identify themselves as procrastinators. A professor believes that the claim regarding college students is too high. The professor conducts a simple random sample of 139 college students and finds that 110 of them identify themselves as procrastinators. Does this evidence support the professor's claim that fewer than 86% of college students are procrastinators? Use a 0.05 level of significance. Step 3 of 3: Draw a conclusion and interpret the decision.
The Bangor Humane Society tracks cat adoptions closely, and in the past has seen 60% of people who come in to look at cats end up adopting cats. They want to know if that percentage has decreased with the social distancing measures in place. Their hypotheses are: Ho: p 2 .60 and Ha: p < .60. They sample 195 people who looked at cats this month and find that 115 of them adopted cats. What is the computed test statistic? Calculate the z or t, whichever is appropriate, and give the result rounded to 2 decimal places. If it's a negative number, put the negative sign before the number with no spaces between it and the number.

A news article that you read stated that 58% of voters prefer the Democratic candidate. You think that the actual percent is smaller. 150 of the 300 voters that you surveyed said that they prefer the Democratic candidate. What can be concluded at the 0.05 level of significance? Interpret the p-value in the context of the study. If the population proportion of voters who prefer the Democratic candidate is 58% and if another 300 voters are surveyed then there would be a 0.25% chance fewer than 50% of the 300 voters surveyed prefer the Democratic candidate. If the sample proportion of voters who prefer the Democratic candidate is 50% and if another 300 voters are surveyed then there would be a 0.25% chance of concluding that fewer than 58% of all voters surveyed prefer the Democratic candidate. There is a 58% chance of a Type I error. There is a 0.25% chance that fewer than 58% of all voters prefer the Democratic candidate. Interpret the level of significance in the context of…

In 2002, the General Social Survey Conducted by StatsSa, participants was asked the following questions. :1. Do you favour or oppose the death of penalty for persons convicted of murder? 2. Do you think the use of marijuana should be made legal or not? If you want to know if there is a relationship between death penalty and marijuana beliefs, what hypotheses should you test? If the Chi-square test statistic = 0.287,what is the appropriate conclusion?
