Independent t-test A researcher wants to know whether people who own dogs are less likely to visit their doctor. A sample of dog owners is compared to a similar group of people (matched for age and health) who are not dog owners. The researcher records the number of visits to the doctor during the past two years for each person. The data is analyzed using SPSS and the following output is obtained: Group Statistics Dog Ownership Std. Deviation Std. Error Mean N.

A study was done to determine whether the proportion of women who had accidents on Friday the 13th was greater than the proportion of men who had accidents on Friday the 13th. To find out, a random sample was taken of 2,000 individuals. Each individual was asked their gender and whether they had been involved in an accident on Friday the 13th. a)What is the explanatory variable, and is it quantitative or categorical? b)What is the response variable, and is it quantitative or categorical? c)What procedure should be used for this test?
In soccer, serious fouls result in a penalty kick with one kicker and one defending goalkeeper. The accompanying table summarizes results from 293 kicks during games among top teams. In the table, jump direction indicates which way the goalkeeper jumped, where the kick direction from the perspective of the goalkeeper. Use a 0.05 significance level to test the claim that the direction of the kick is independent of the direction of the goalkeeper jump. Do the results support the theory that because the kicks are fast, goalkeepers have no time to react, so the directions of their jumps are independent of the directions of the kicks? Click the icon to view the penalty kick data. Determine the null and alternative hypotheses. O A. Ho: Goalkeepers do not jump in the direction of the kick. H₁: Goalkeepers jump in the direction of the kick. O B. Ho: Goalkeepers jump in the direction of the kick. H₁: Goalkeepers do not jump in the direction of the kick. O C.

A TA in statistics thinks that the format of the conferences and the timing of the assignments may affect students' assignment marks (out of 10). He decided to design three conferences with a different format: (1) with lecturing, (2) with demonstrating problems, and (3) with involving students in active problem-solving. Twelve students attended one of the conferences (four in each format) and asked to submit their assignments at week 3. Another twelve students attended one of the conferences but asked to submit their assignments at week 5. The data are tabled below: Assignment Week 3 Week 5 Lecture 6,7,5,7 5,5,4,5 Format Demo problems 7,8,8,9 6,7,7,6 Active problems 9,10,10,10 8,9,9,10 Note: ΣΣΣx=1385 Perform the ANOVA test and table the results, stating all critical values. State and explain what should be the follow-up analysis after the overall F-test if any (NO calculation but just explain).

A skin patch contains a new drug to help people quit smoking. A group of 75 cigarette smokers have volunteered as subjects to test the new skin patch. For one month, 40 of the volunteers receive skin patches with the new drug. The other volunteers receive skin patches with no drugs. At the end of the two months, each subject is surveyed regarding his or her current smoking habits. (Select all that apply.) a) No placebo is being used.b) Then record the smoking habits of all volunteers to see if a difference exists between the two groups.c) Then record the smoking habits of the 40 volunteers to see if a difference exists between the two groups.d) Use random selection to pick 40 volunteers for the skin patch with the drug.e) Use random selection to pick 35 volunteers for the skin patch with the drug.f) A placebo patch is used for the remaining 35 volunteers in the second group.g) Then record the smoking habits of the 35 volunteers to see if a difference exists between the two groups.
ific Calculator Of30shg/ckivdfk1p00003g5tgeftOid1 Agroup of researchers in New York wants to test if there is any relationship between living in California and preferring warm weather to cold weather. The researchers send out an online questionnaire to 200 randomly chosen people in the US asking several questions including: "Do you live in California?" and "Do you prefer warm weather to cold weather?". The results are summarized in the table below: Prefers Warm Weather 80 Prefers Cold Weather 42 Lives in California Doesn't Live in California 35 43 Test the null hypothesis that the choices on these two questions are independent versus the alternative that they are dependent.

Moral judgments about a harmful behavior are expected to be associated with one’s ability to recognize how hurt the victim of the harmful behavior is. To test this a replication of the Malti and colleagues (2012) was attempted. Researchers asked 12- and 15-year-olds whether they thought it was okay to exclude a Serbian peer from going to a soccer match (1 = really not okay, 7 = really okay) and how they thought the Serbian peer would feel if he/she was not invited to the soccer match (1= very bad, 7 = very good). The results for 12 of these adolescents are below: 1. Find the correlation, r, between exclusion judgments and evaluations of the victim’s feelings (assuming the researcher wanted to use the 1 to 7 scale as a numerical interval score). Q: r= ? 2. Describe this correlation and what does this correlation indicate about the relation between exclusion judgments and evaluations of the victim’s feelings?

Liam is conducting a market research study to determine the effectiveness of advertisements on social networking sites. He surveyed a randomly selected group of 2,000 young adults on how likely they are to purchase from a company based on its advertisements on social networking sites. Respondents rated their likelihood to purchase on a scale from 1 to 7, with 1 being "Not at all likely" and 7 being "Definitely." The results are summarized in the bar graph above. Which of the following state- ments is NOT true based on the survey results?

Which of the following statements is true? 1) You cannot determine from the information given. O 2) The relative risk of getting exposed to contaminated water is 12.6 times more likely than those who lived elsewhere. 3) 15 of the cases can be attributed to contaminated water. 4) Only half of the citizens are at risk.
