A recent report claimed that 13% of students typically walk to school. DeAnna thinks that the proportion is higher than 0.13 at her large elementary school. She surveys a random sample of 100 students and finds that 17 typically walk to school. DeAnna would like to carry out a test at the a = 0.05 significance level of Но : р %3D 0.13 На : р> 0.13 where = the true proportion of all students at her elementary school who typically walk to school. What conclusion would you make? Because the P-value of 0.1170 > a = 0.05, we fail to reject Ho. We have convincing evidence that the true proportion 0• of all students at this elementary school who typically walk to school is greater than 0.13. Because the P-value of 0.1170 > a = 0.05, we fail to reject Ho. We do not have convincing evidence that the true proportion of all students at this elementary school who typically walk to school is greater than 0.13. Because the P-value of 0.1170 > a = 0.05, we reject Họ. We do not have convincing…
Read through this scenario and look at the data that was collected. State the null and all possible research hypotheses. Review the results below (I used SPSS) and answer the questions that follow. Scenario: A researcher wants to see if gender and / or income affects the total amount of help given to a stranger who is sitting on the side of a busy road with a sign asking for help. The independent variables are gender, income, and the interaction of gender and income. The dependent variable is total help. He wants to know if one or both factors – or the interaction of the two - affects the total amount of help offered. Because he is analyzing two independent variables (gender and income), he used a factorial ANOVA. His results show the main effect of each of the independent variables on the dependent variable (total help) and the interaction effect. The researcher is using a 95% confidence interval which means that he wants to be at least 95% sure that his independent variables…
A recent college graduate is trying to decide whether or not pursuing a Master's degree is worth it. He decides examine this question at the a 0.05 level of significance, by comparing the salaries of a random sample of adults with only a Bachelor's degree to a random sample of adults with a Master's degree to see if the adults with a Master's degree earn more money. Let uB represent the average salary of an adult with a Bachelor's degree only and uM represent the average salary of an adult with a Master's degree. Which would be correct hypotheses for this test?

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 0.05 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?
