Suppose 224 subjects are treated with a drug that is used to treat pain and 52 of them developed nausea. Use a 0.1 significance level to test the claim that more than 20% of users develop nausea. a) Identify the null and alternative hypotheses for this test. b) Identify the test statistic for this hypothesis test. c) Identify the P-Value for this hypothesis test. d) Identify the conclusion for this hypothesis test. 1) Reject. There is not sufficient evidence to warrant the support of the claim that more than 20% of users develop nausea. 2) Fail to reject. There is sufficient evidence. 3) Fail to reject. There is not sufficient evidence. 4) Reject. There is sufficient evidence.
In a recent study, researchers found that 31 out of 150 boys aged 7-13 were overweight or obese. On the basis of this study can we conclude that more than 15% of the boys aged 7-13 in the sampled population are overweight or obese? Use a 5% level of significance. Give each of the following to receive full credit: 1) the appropriate null and alternative hypotheses; 2) the appropriate test; 3) the decision rule; 4) the calculation of the test statistic; and 5) your conclusion including a comparison to alpha or the critical value.

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.
Mitt Romney was a presidential candidate in the Novem-ber 2012 U.S. presidential elections and he is a Mormon. The Public Religion Research Institute, during its 2011American Values Survey, asked 1019 random Americansif they would be comfortable with a Mormon serving asPresident. Fifty three percent reported that they wouldbe somewhat or very comfortable with this. Which ofthe following hypotheses should we test to determinewhether the majority of Americans would be somewhator very comfortable with a Mormon serving as president?A) H0 : p = 0.50 HA: p ≠ 0.50B) H0 : p = 0.50 HA: p 6 0.50C) H0 : p = 0.50 HA: p 7 0.50D) H0 : p = 0.53 HA: p 7 0.53E) H0 : pn = 0.53 HA: pn ≠ 0.53(Source: http://publicreligion.org/research/2011/11/2011-american-values-survey/)
Do the needs of patients in the emergency room differ for those who come by car vs. those by ambulance? Of the randomly selected emergency room patients who came by car 51 had an injury, 40 were sick, 31 had heart problems and 61 had other needs. Of the randomly selected emergency room patients who came by ambulance 45 had an injury, 30 were sick, 55 had heart problems and 38 had other needs. Conduct the appropriate hypothesis test using an a = 0.10 level of significance. a. What is the correct statistical test to use? O Paired t-test O Homogeneity Goodness-of-Fit O Independence b. What are the null and alternative hypotheses? Ho: O Means of transportation to the emergency room and emergency room needs are independent. Means of transportation to the emergency room and emergency room needs are dependent. The distribution of emergency room needs for patients who come by car is the same as it is for patients who come by ambulance. The distribution of emergency room needs for patients who…

2. a). The term error is used in two different ways in hypothesis testing: a Type I error (or Type II) and the standard error. What can a researcher do to influence the size of the standard error? Does this action have any effect on the probability of a Type I error? b). What are the major steps involved in hypothesis testing?
Legalization of marijuana, bootstrap test. The 2018 General Social Survey asked a random sample of 1,563 US adults: â€œDo you think the use of marijuana should be made legal, or not?â€ 60% of the respondents said it should be made legal. (NORC 2018) Consider a scenario where, in order to become legal, 55% (or more) of voters must approve. What are the null and alternative hypotheses for evaluating whether these data provide convincing evidence that, if voted on, marijuana would be legalized in the US.
A study was conducted to determine the proportion of people who dream in black and white instead of color. Among 285 people over the age of 55, 76 dream in black and white, and among 287 people under the age of 25, 10 dream in black and white. Use a 0.01 significance level to test the claim that the proportion of people over 55 who dream in black and white is greater than the proportion for those under 25. Test the claim using a hypothesis test. Consider the first sample to be the sample of people over the age of 55 and the second sample to be the sample of people under the age of 25. What are the null and alternative hypotheses for the hypothesis test? O A. Ho: P1 = P2 H: P1> P2 O B. Ho: P1 = P2 OC.

Minnesota had the highest turnout rate of any state for the 2016 presidential election.† Political analysts wonder if turnout in rural Minnesota was higher than turnout in the urban areas of the state. A sample shows that 627 of 836 registered voters from rural Minnesota voted in the 2016 presidential election, while 414 out of 575 registered voters from urban Minnesota voted. (a) Formulate the null and alternative hypotheses that can be used to test whether registered voters in rural Minnesota were more likely than registered voters in urban Minnesota to vote in the 2016 presidential election. (Let p1 = the population proportion of voters in rural Minnesota who voted in the 2016 election and p2 = the population proportion of voters in urban Minnesota who voted in the 2016 election.) (b) What is the proportion of sampled registered voters in rural Minnesota that voted in the 2016 presidential election? (c) What is the proportion of sampled registered voters in urban…
In a survey of 1,000 women age 22 to 35 who work full-time, 555 indicated that they would be willing to give up some personal time in order to make more money. The sample was selected to be representative of women in the targeted age group. (a) Do the sample data provide convincing evidence that a majority of women age 22 to 35 who work full-time would be willing to give up some personal time for more money? Test the relevant hypotheses using a = 0.01. State the appropriate null and alternative hypotheses.
