QUESTION 13You are interested in seeing whether emotions impact decision making. You have three groups--a happy group, a sad group, and aneutral group. For the happy group there are 5 participants and the mean risky decision making score 5.0 with a standard deviationof 0.7. For the sad group there are 5 participants and the mean risky decision making score 5.4 with a standard deviation of 1.1. Forthe neutral group there are 5 participants and the mean risky decision making score 5.8 with a standard deviation of 2.8.The sum of squares between samples is equal to 1.6. The sum of squares within samples is equal to 38.0. You calculated the f-ratioabove. The corresponding p-value for the f-ratio you calculated is p = 0.78. Do you accept or reject the null hypothesis?O You accept the null hypothesis because your p-value is greater than .05 and not significant.O You reject the null hypothesis because your p-value is greater than .05 and significant.O You accept the null hypothesis because your p-value is greater than .05 and significant.O You reject the null hypothesis because your p-value is greater than .05 and not significant.

In a study examining the relation of math ability to the belief that math ability was innate, the belief was considered the predictor variable. The researcher hopes to find a correlation between the participants’ math ability and their belief that math ability is innate. The scores for the three participants are shown below. The group that believed that math is NOT innate scored 66, 70, 50. The group that believed that math IS innate scored 7, 4,10. what are the mean and SD for each group?

A psychologist wanted to know if students in her class were more likely to cheat if they were low achievers. She divided her 60 students into three groups (low, middle, and high) based on their mean exam score on the previous three tests. She then asked them to rate how likely they were to cheat on an exam if the opportunity presented itself with a very limited chance for consequences. The students rated their desire to cheat on a scale ranging from 1-100, with lower numbers indicating less desire to cheat. Before opening the data, what would you hypothesize about this research question? Open the data set. Before running any statistical analyses, glance through the data. Do you think that your hypothesis will be supported? Conduct descriptive analyses and report them here. Conduct a one-way ANOVA. Report your statistical findings (including any applicable tables in APA format) here. What would you conclude from this analysis? What would be your next steps, if this…
Dr. Springer collected data to see whether people who eat an all-carbohydrate meal have different scores on a mood scale than people who eat an all-protein meal. Higher scores represent better moods. Here are her results: All Carbs All Protein 10 7 8 4 7 9 9 28 13 13 7 7 12 Is there a difference in reported mood between the two groups? Use a two tailed test with an a = 0.05. Step 4: Make a decision Our test statistic has a value of t = I , and in Step 2 we found that the critical value is t* = the null hypothesis Therefore, we (write: reject or fail to reject)
Research indicates that stress levels are lowered when petting a dog. . A mood inventory questionnaire is administered to a group of 20-29 - year olds with no do present in the room, and again a month later the same mood questionnaire is administered to the same people with a dog present in the room. Is there a significant difference in the mood scores for when the dog was present or not? Test with a = .05 for two tails. Person No Dog in Room Dog in Room A 12 14 B 8 7 C 10 13 D 9 9 E 7 13 F 10 12

Suppose you were to collect data for the following pair of variables, drivers: blood alcohol level, reaction time. You want to make a scatter plot. Which variable would you use as the explanatory variable? Blood alcohol or reaction time? Which variable would you use as the response variable? Blood alcohol or reaction time? Would you expect to see a positive or negative association? Or neither?
You need to use Stata to look up the dataset and its variables. Use Stata Companion Textbook. (Dataset: NES. Variables: spend8, [pw=nesw].) The NES dataset contains spend8, which records the number of government policy areas where respondents think spending should be increased. Scores range from 0 (the respondent does not want to increase spending on any of the policies) to 8 (the respondent wants to increase spending on all eight policies). The NES, of course, polls a random sample of U.S. adults. In this exercise you will analyze spend8 using the mean and lincom commands. You then will draw inferences about the population mean. (Remember to specify nesw as the probability weight.) The spend8 variable has a sample mean of ______. Make sure you use [pw=nesw] so your results are nationally representative. There is a probability of .95 that spend8’s true population mean falls between a score of ______ at the low end and a score of ______ at the high end. A student researcher…
