Question Answered step-by-step There are lots of techniques that we can use to try to calm down or…  There are lots of techniques that we can use to try to calm down or relax when we are feeling anxious or tense. One strategy is deep breathing (see this link for some tips on deep breathing, https://www.uofmhealth.org/health-library/uz2255Links to an external site.). A professor is interested in examining how deep breathing can influence feelings of anxiety. She recruits participants in her class right before the final exam, when their feelings of anxiety would be high. She measures their current levels of anxiety, instructs them to engage in 2 minutes of deep breathing, and then measures their anxiety again after they’ve completed the breathing. Below are the anxiety levels of each student before and after deep breathing. Your job is to determine if their anxiety levels significantly DECREASE after deep breathing.Data tableBefore Deep BreathingAfter Deep Breathing1510108115141012843721-What’s the null hypothesis for this research question? Group of answer choicesHo: Anxiety levels before deep breathing ≤ anxiety levels after deep breathingHa: Anxiety levels are significantly lower after deep breathing 2-What’s the alternative hypothesis for this research question? Group of answer choicesHa: Anxiety levels are significantly lower after deep breathingHo: Anxiety levels are the same before and after deep breathing 3-What’s the best statistical test to use to analyze this research question? Group of answer choicesa) One sample z-testb) Dependent samples t-test c) F statistic d) Correlation coefficiente) Independent sample t-testf) One way ANOVA 4-The next step is to compute the test statistic. What is the t-statistic value (make sure you’re using the t-test formula for the dependent samples t-test). Round your answer to two decimal places.  5-What are the degrees of freedom?  6-Should a one-tailed or two-tailed test here? Think about whether the hypothesis is directional or non-directional! Group of answer choicesa) two tailedb) one tailed 7-What is the critical value?  8-Based on the t-value provided and the critical value, what is your decision about this research study?Group of answer choicesa) There is a significant decrease in anxiety after deep breathingb) There is not a significant decrease in anxiety before and after deep breathing. 9-Write up your results as you would see them in an  style write up. Don’t forget to include your means and sds for the before and after data!             Social Science Psychology MAR 1931 Share QuestionEmailCopy link Comments (0)
