Suppose you are given a sample of 50 people with their height and weight data, and you want to test the hypothesis that there is no significant relationship between height and weight. What is the critical value of Pearson's r at 0.05 significance level?
Can you help me solve this question. I am unable to access the other two questions because you have to include an answer first.
should we accept or reject the null hypothesis at a significance level of 0.05? Explain.
According to the most recent General Social Survey, 70% of adults watch TV nightly. A researcher believes that the proportion of college students who watch TV nightly is less than this. To test this claim the research samples 400 college students and finds that 276 watch TV nightly. At the 0.05 level of significance does this data provide evidence to suggest that the proportion of college students who watch TV nightly is less than 70%? Select the correct conclusion for the hypothesis test: Question 12 options: Fail to reject the null hypothesis because the p-value is less than the level of significance. Fail to reject the null hypothesis because the p-value is greater than the level of significance. Reject the null hypothesis because the p-value is less than the level of significance. Reject the null because the p-value is greater than the level of significance.
You are hired by a university health services department to examine the relationship between flu vaccinations and number of class absences among college students. Please complete steps 1 through 3 of the hypothesis testing process. State the Research Hypothesis. Be sure to indicate whether this is a one-tailed or two-tailed hypothesis. State the Null Hypothesis. Specify the Rejection Level. Be sure to indicate why you chose this rejection level.
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…
If your question is that your significant hypothesis test is significant “enough” to have true meaning, what are some other things you can look at to determine practical significance?
Identify the appropriate hypothesis test for each of the following research situations labeled (a) - (d). Make sure to label your responses clearly! A researcher conducts a study to determine whether there is a significant difference in life satisfaction between bisexual men and gay men. A researcher records the weekly alcohol consumption and the number of violent crimes committed by incarcerated adolescents. The researcher would like to determine whether there is a significant relationship between their teen’s alcohol A researcher would like to determine the effectiveness of her newly designed mnemonic training, a technique that is expected to improve memory. She selects a sample of n=30 participants, tests their memory skills then has them undergo the training for 4 hours. At the end of the training, participants’ memory skills are tested a second time. A researcher would like to determine whether gender (Male, Female) and sexual orientation (Gay, Bisexual, Heterosexual) affect…
In general, if sample data are such that the null hypothesis is rejected at the ? = 1% level of significance based on a two-tailed test, is H0 also rejected at the ? = 1% level of significance for a corresponding one-tailed test? Explain your answer. Yes. If the two-tailed P-value is smaller than ?, the one-tailed area is also smaller than ?. No. If the two-tailed P-value is smaller than ?, the one-tailed area will be larger than ?. Yes. If the two-tailed P-value is smaller than ?, the one-tailed area will be larger than ?. No. If the two-tailed P-value is smaller than ?, the one-tailed area is also smaller than ?.
A researcher wants to investigate the effect of anti-anxiety medication on depression. To do so, she gives one group a placebo treatment and one group the medication. Which hypothesis test is appropriate for her study? A. One-way ANOVA B. Two-way ANOVA C. Independent-samples t-test D. Related-samplest-test
A nutrition expert claims that the average American is overweight. To test his claim, a random sample of 29 Americans was selected, and the difference between each person's actual weight and idea weight was calculated. For this data, we have x = 15.7 and s = 29.9. Is there sufficient evidence to conclude that the expert's claim is true? Carry out a hypothesis test at a 9% significance level. Hint: Pay attention to the variable being measured: the difference between actual weight and ideal. A positive value indicates that the person is overweight. %3D A. The value of the standardized test statistic (give to 3 decimal places): B. The p-value is (give to 4 decimal places): C. Your decision for the hypothesis test: O A. Reject Ho. O B. Do Not Reject Ho. C. Do Not Reject Ha. O D. Reject Ha.
You are a research assistant at a zoo. The question of your study is "Has the proportion of baby zebras born in zoos has changed from 10%?". Your supervisor asks that you run a hypothesis test using an significance level of 0.05. Form the study you obtain a z-score of 0.788. Do you reject the null hypothesis and why?
