2. Independent Sample T-Test: A researcher is interested in the anxiety levels ofindividuals who get in-home counseling vs those who get out-of-home counseling. Theresearcher measures participant anxiety scores by using questionnaire measured on a scalefrom 1-10. The researcher manages to gather a sample of 40 participants. Use a = 0.05In-Home Out-of-Home1513433146514436777886777554652436754387 In this test you will conduct and interpret T-tests using hypothesis testing and the SPSSprogram.Students will follow the hypothesis testing steps for each problem. They will compute theproblem using the SPSS program. They will write the results in appropriate APA format andinterpret the results. Steps of hypothesis testing will be typed out in a word document, as weas a copy and paste of the SPSS output.For the following problems, you will:Do all steps of hypothesis testingO Write out the hypothesesOWrite out the steps you would do to calculate tOChoose the t-cutoff scoreOCalculate the t-statistic using the computer program SPSS, include effect sizeWrite the t-statistic using proper APA formatDecide whether or not you would reject the null hypothesis●OInterpret this resultBe sure to include a copy of the SPSS output in the word document

Of 94 patients who said they did not exercise regularly, 48 reported falling in the previous six months. Can you conclude the proportion of patients who fall is less for those who exercise than for those who do not? Use the significance level of 0.05. Type the Computed Testing.

Proportions On April 15th, 1912, the R.M.S. Titanic sank into the North Atlantic Ocean, resulting in the loss of more than 1,500 passengers and crew. Below is a table which summarizes the total number of passengers and the number of survivors for the crew, first-, second-, and third-class. Find the proportion of survivors by type of service (crew, first, second, third). Test the hypothesis at the 95% confidence level that the proportion of first-class survivors is the same as .50. What do you calculate for the test-statistic? What is the critical statistic? What is the conclusion of your hypothesis test?

p = proportion of students who drop out due to lack of economic resources A sociologist thinks that in his country the percentage of students who drop out due to lack of economic resources is different from 40%. He takes a sample of 70 student dropouts and finds that 37 of them dropped out due to lack of financial resources.Can the sociologist, with a significance level of 0.05, consider that the percentage of students who drop out due to lack of economic resources is different from 40%? Choose 1. The correct conclusion2. The correct interpretationSelect one:to)1. H0 is rejected2.

Adverse reactions of a drug used to help patients continue their abstinence from the use of alcohol have been studied in clinical trials, and the accompanying table summarizes results for digestive system effects among patients from different treatment groups. Use a 0.05 significance level to test the claim that experiencing an adverse reaction in the digestive system is independent of the treatment group. Does the drug treatment appear to have an effect on the digestive system? Click the icon to view the data on adverse reactions from treatments. Determine the null and alternative hypotheses. OA. Ho: Drug treatment and adverse effects are not independent. H₁: Drug treatment and adverse effects are independent. OB. Ho: The drug treatment results in adverse effects on the digestive system.
