DIRECTIONS: 2. Identify the appropriate hypothesis test for each of the following research situations labeled (a) - (d). Make sure to label yourresponses clearly!(a) A researcher conducts a developmental study to determine if there is a significant difference in social skills between 9-year-old and 11-year-old children.(b) A researcher records the daily caffeine consumption and the activity level of a group of college freshman. The researcher would liketo determine whether there is a significant relationship between caffeine level and activity.(c) A researcher would like to determine whether a 4-week therapy program produces significant changes in behavior. A group of 25participants is measured before therapy, at the end of therapy, and again 3 months after therapy.(d) A researcher would like to determine whether a new program for teaching statistics is significantly better than the old program. It issuspected that the new program will be very effective for small-group instruction but less effective with larger classes. The study involvescomparing four groups of students: a small class taught in the new method, a small class taught in the old method, a large class taught in thenew method, and a large class taught in the old method.

7. For each of the following, indicate the appropriate hypothesis test (one-sample z-test, one-sample t-test, independent-measures t-test, or dependent-measures t-test). If your response is dependent-measures t-test, indicate the "flavor" of the dependent measures t-test. d. A different researcher also conducts a study involving relaxation training. Baseline levels of test anxiety are recorded for a sample of subjects. Then all subjects receive relaxation training for 3 weeks and their anxiety levels are measured again. e. In a test anxiety study, two samples are used. Subjects are assigned to groups so they are matched for self-esteem and grade-point average. One sample receives relaxation training for three weeks and the second serves as a no-treatment control group. Test anxiety is measured for both groups at the end of three weeks.
If the results of the test with the following hypotheses are statistically significant, we have found evidence that: Hypotheses: Ho :H1 = H2 Ha:H1>H2 Hi = H2 X1H2 X1 # X2 X1>X2 Hi
It has recently been claimed that 25% of adults consider spring to be their favorite season of the year. A researcher is skeptical of this claim and believes this percentage is too low. She surveys a random of 1,000 adults and finds that 390 of these adults consider spring to be their favorite season of the year. As she prepares to conduct a hypothesis test, the researcher writes out her alternative hypothesis as “p < 0.25.” What is wrong with this? The alternative hypothesis should be “p > 0.39.” The alternative hypothesis should be “p < 0.39.” The alternative hypothesis should be “p > 0.25.” The alternative hypothesis should be “p = 0.25.” Nothing is wrong with the given alternative hypothesis.
Suppose a certain state university's college of business obtained the following results on the salaries of a recent graduating class: Finance Majors Business Analytics Majors n = 140 n2 = 30 X, = $48,137 X2 = $55,417 s1 = $19,000 s, = $10,000 (a) Formulate hypotheses so that, if the null hypothesis is rejected, we can conclude that salaries for Finance majors are significantly tower than the salaries of Business Analytics majors. Use a = 0.05. (Let µ, = the population mean salary for Finance majors, and let u, = the population mean salary for Business Analytics majors. Enter != for # as needed.) Ho

Imagine you are doing a Related-Samples t-test, and you are on Step Two of the hypothesis test. The sample of difference scores that you calculated is -1, -1, -3, +2, 0, -4. If you are doing the test with α = .01, and two tails, what would he correct t-critical be?
A group of n = 8 students wants to know if the commuting time from home to college by bus is less than the commuting time by car. For this, each of them recorded the time spent using each means of transport. Recorded travel times are shown below. Each pair of values refers to a student, the first value being the time spent by car and the second by bus (both in minutes). Proceed with a hypothesis test appropriate to the significance level α=6%. studen 1 2 3 4 5 6 7 8 Car 15 20 20 20 17 15 10 18 bus 10 22 15 20 12 10 12 10 Difference 5 -2 5 0 5 5 -2 8 a. The test hypotheses in this study are: H0: μd=μCar−μBus=0 and Ha: μd=μCar−μBus > 0?b. The test statistic value calculated based on the data is:c. The critical (absolute) value of the test for the desired significance level is:
1. The incidence of cancer among phosphate mine workers and their exposure to radiation was investigated. Cancer incidence was recorded among 60 phosphate mine workers who had 0-29 working level months (WLM) of exposure, 60 phosphate mine workers who had 30-89 WLM of exposure, and 60 phosphate mine workers who had 90-120 WLM of exposure. The number of cancer incidences for each group are presented in Table 1. Table 1: Two-way Table of Counts Cancer Incidence Exposure Level Yes No Total 0-29 WLM 20 40 60 30-89 WLM 33 27 60 90-120 WLM 43 17 60 Total 96 84 180 Perform a x? test, at the 5% level of significance, whether cancer incidence rates differ between the three levels of radiation among phosphate mine workers.
These are the answer selections for the drop-down boxes. The hypothesis test will be (two tailed, left-tailed, right-tailed) Reject the (alternative, null) hypothesis that the proportion of people who read books in print is (less than, equal to, greater than, not equal to) 0.25 in which case there is evidence (in support of, to reject) Do not reject the (null, alternative) hypothesis, in which case there is not enough evidence to (reject, support)the claim that the proportion of people who read books in print is not equal to 0.25.
I only want the correct answer for the question it’s urgent please!!!
Imagine you are doing a Related-Samples t-test, and you are on Step One of the hypothesis test. If you are doing the test with α = .05, and two tails, how would the H0 (null hypothesis) look?
In this assignment students will demonstrate their understanding of the distribution of means doing all steps of hypothesis testing. For each problem students will write out all steps of hypothesis testing: 1. State the null and research hypotheses. 2. Set the level of risk associated with the null hypothesis. 3. Select the appropriate test statistic. 4. Compute the test statistic value (called the obtained value). 5. Determine the value needed for rejection of the null hypothesis using the appropriate table of critical values for the particular statistic. 6. Compare the obtained value and the critical value. 7. Make your decision. After completing of the steps of hypothesis tests, write out your results in APA format and in easy-to-understand language 3.
