(6pts) “We found that with the new learning method students generated averagely 4.3 ideas (SD=1.67) when completing the social psychology reading. A one-sample t test showed that the population mean number of ideas generated was significantly higher than the typical level of 2.28 ideas found previously, t(28) = 6.52, p<.01.” Please fill out the information below with the numerical values provided in the above question: 1) from the null hypothesis (i.e., 0) = 2) N= 3) = 4) s= 5) = 6) Was the null hypothesis rejected? Yes/No (Please choose) 2. (5pts) We found no difference on the reported self-esteem level between female participants (M=5.39, SD = .83) and male participants (M = 5.50, SD = .78), t (152) = -.86, p=.393. 1) What was the design of this study? Between-subjects/Within-subjects (Please choose) 2) What was the DV (variable of interest)? 3) How many participants were included in the analysis? 4) In average, what was male participants’ reported self-esteem level in this study? 5) Was the null hypothesis rejected? Yes/No (Please choose) 3. A nutritionist in the FDA wants to compare the caloric content of medium French fries sold by Wendonald (Population 1) and McKing (Population 2) fast-food chains, to see if there is any difference between them. To test this, random samples from each chain is taken and the caloric contents of French fries are measured. The finding is summarized in the table on next page. Conduct an independent-samples t test to test whether there is any difference between the caloric content of French fries sold by the two chains, following the steps below. Wendonald McKing = 40 = 50 = 380 calories = 360 calories = 30 calories = 38 calories a. (2pts) Write down the null and alternative hypotheses using proper notation b. (4pts) Calculate (Write all steps) c. (2pt)What is the value of for α = 0.05 with a two-tailed test? d. (3pts) Suppose your calculated t statistic is 2.90 (Note this is a hypothetical situation, not the actual result from your test), what decision do you make with respect to the statistical hypotheses for this study? State your interpretation with reference to the question asked. Decision: Interpretation: 2. Below are 5 participants’ ratings of how likable two comedians were.
