Example: Assume that adults were randomly selected for a poll. They were asked if they "favor or oppose using federal tax dollars to fund medical research using stem cells obtained from human embryos.” Of those polled, 480 were in favor and 394 were opposed. A politician claims that people don’t really understand the stem cell issue and their responses to such questions are random responses equivalent to a coin toss. Use a 0.01 significance level to test the claim that the proportion of subjects who respond in favor is equal to 0.5. What does the result suggest about the politician’s claim? Following the hypothesis test steps, let’s first identify the claim and the null and alternative hypotheses: For this example, the original claim is that the proportion of the subjects who responded in favor is equal to 0.5 (half – since the politician compared their responses as equivalent to a coin toss). The symbolic form of the politician’s claim can be expressed as p = 0.5. Also notice…
Another question asked for a ranking of the condition of the road, based on the type of road. For the road types of interstate highway, U.S. highway, state (“M") highway, and local roads, residents were asked to evaluate the current condition, with choices of good, bad, or neutral. Researchers wish to evaluate if there is some relationship between the type of road and the road condition. This is a O Hypothesis test O Confidence interval For One proportion One mean O Paired mean O Difference in two means O Slope for a linear relationship O Chi-square goodness-of-fit O Chi-square test of independence
Determine if the survey question is biased. If the question is biased, suggest a better wording. How often do you eat vegetables during an average month? Is the question biased? OA. Yes, because it does not lead the respondent to any particular answer. A better question would be "Why is eating vegetables good for you?" OB. Yes, because it influences the respondent into thinking that eating vegetables is good for you. A better question would be "Do you think that eating vegetables is good for you?" OC. No, because it influences the respondent into thinking that eating vegetables is good for you. OD. No, because it does not lead the respondent to any particular answer.
Using SPSS, analyze the relationship between respondents’ marital status (MARITAL) and whether they believe it is alright for a couple to live together without intending to get married (COHABOK) using crosstabulation. Which marital status category is most disapproving of nonmarital cohabitation? Which marital status category is most approving of nonmarital cohabitation? Is the relationship between marital status and attitude toward nonmarital cohabitation statistically significant at the .05 level? Compute and interpret an appropriate measure of association for this relationship.
Anterior cruciate ligament (ACL) injuries occur most frequently in planting and cutting sports such aa basketball, soccer, and volleyball. A sports medicine researcher wants to test if female athletes are more likely to have an ACL injury than males. He surveyed 50 collegiate programs that had both men's and woman's volleyball and asked them how many grade 3 ACL tears they had during the past season. Which statistical test would be best to determine if there is a significant diffence between groups? One sample t test Dependent samples t test Independent samples t test ANOVA
A political scientist claims that 38% of first-year college students characterize themselves as being “moderate” or “middle of the road” as far as their political affiliation is concerned. Believing this claimed value is too high, you survey a random sample of 400 first-year college students and find that 120 characterize themselves as being “moderate” or “middle of the road.” Based on this information, what will the test statistic be? Choose the answer below that is closest to what you calculate, and try not to do a lot of rounding until you get to the very end of your calculations. 1. -0.3 2. -1.2 3. -2.6 4. -3.3 5. None of the other answer options are correct because the test statistic should be positive, not negative.
Many people believe that criminals who plead guilty tend to get lighter sentences than those who are convicted in trials. The accompanying table summarizes randomly selected sample data for defendants in burglary cases. All of the subjects had prior prison sentences. Use a 0.05 significance level to test the claim that the sentence (sent to prison or not sent to prison) is independent of the plea. If you were an attorney defending a guilty defendant, would these results suggest that you should encourage a guilty plea? Guilty Plea Not Guilty Plea Sent to Prison 418 48 Not Sent to Prison 558 43
Question Bias Which of the following survey questions would NOT show bias? Select one: Don't you agree that eating whole grain food improve your O a. health? O b. How much do you exercise during an average week? O c. If someone is distracted by text messaging while they are driving, are they more likely to have an accident? O d. Is outsourcing of jobs to other countries justified if it takes away current jobs from American citizens.
Explain in detail RANDOM ASSIGNMENT OF SUBJECTS.
Internet Doctors: Hypothesis Test Use the survey results given in Exercise 1 and use a 0.05 significance level to test the claim that the majority of adults learn about medical symptoms more often from the Internet than from their doctor.
One of the theories behind the large polling errors in 2016 election was the "shy Trump voter". According to this explanation, many respondents voted differently than what they told the pollsters.
