Question

1. A relationships researcher (who double majored in English and Psychology as an undergraduate) recalled a well-known phrase from a poem by Alfred, Lord Tenyson, that in the spring, a young person’s fancy turns to thoughts of love. She specifically wanted to test the hypothesis that students are more likely to be distracted by thoughts of romance in the spring than in the fall. She selected a random sample of 12 college students. She measured distractedness via a reaction time test on a computer, where the participants were to press the space bar as soon as they find a target stimulus on the screen that was hidden in a field of distractor stimuli. The software recorded the reaction time elapsed to in milliseconds—where longer reaction times indicate more distraction. The researcher held the time in the semester constant by running the participants in the experiment during midterm exams in both the fall and the spring semesters. Was Lord Tenyson’s poem correct?

Identify the appropriate statistical test. staple b. State the null and alternative hypotheses. c. What is the critical value of the test statistic? What is the decision rule for rejecting the null hypothesis? CV: _________________________ Reject H0 if t _____________________ d. Paste in your SPSS output here. Circle the means, standard error, and observed value of t on the output. Show your work for t observed (using formula and plugging in appropriate numbers from output) and eta2 here: tobs= eta2 = e. Write out an APA Style conclusion about the research project, using the context of the study in your answer. anyone know where to start?

Answer 1

a) We would use paired t-test to identify the romance distract students in spring than in fall.

b) Hypothesis would be as followed:

H₀: µ₁>µ₂

H₁:µ₁<µ₂

c) Decision rule, when t-value is less than t-sig. we may not reject the null hypothesis.

d) the data would be as followed:

Analysis(Output) on SPSS is given by:

According to the given analsis and by keeping in mind the decision rule, we may not reject the null hypothesis which means that it is possible that students distract in romance at the spring more in compare to the fall.
