QUESTION 8You hypothesize that drinking tea reduces stress levels so you design a study comparing stress levels between people who drink teaand people who do not drink tea. You collect data on 47 people and find that in your sample there are 21 people who do not drink teaand 26 people who drink drink tea. The mean stress score for non-tea drinkers is 76 with a standard deviation of 25, while the meanscore for those who drink tea is 62 with a standard deviation of 13. Use the chart on page 557 of your textbook to determine the criticalvalue of t at a p = .05 level (two-tailed test). Enter this value exactly as it appears in the critical values of t chart (three decimals).QUESTION O

We often describe our emotional reaction to social rejection as “pain.” A clever study asked whether social rejection causes activity in areas of the brain that are known to be activated by physical pain. If it does, we really do experience social and physical pain in similar ways. Subjects were first included and then deliberately excluded from a social activity while changes in brain activity were measured. After each activity, the subjects filled out questionnaires that assessed how excluded they felt. Here are data for 13 subjects. The explanatory variable is “social distress” measured by each subject’s questionnaire score after exclusion relative to the score after inclusion. (So values greater than 1 show the degree of distress caused by exclusion.) The response variable is change in activity in a region of the brain that is activated by physical pain. create a scatterplot
You hypothesize that people in stats classes are happier than people in all other classes. You compare happiness scores in three of your classes: Statistics, Developmental Psychology, and Social Psychology. In Statistics there are 15 students and the mean happiness rating is 23.1 with a standard deviation of 9.78. In Developmental Psychology there are 15 students and the mean happiness rating is 24.4 with a standard deviation of 2.92. In Social Psychology there are 15 students with a mean rating of 17.7 and standard deviation of 8.46. The sum of squares between groups is equal to 384. The sum of squares within groups is equal to 2461. Use the One-Way ANOVA calculation table to help calculate. What is the degrees of freedom within samples?

For each case below, state what type of statistical test you would use to analyze each dataset. Explain your answer! Hemoglobin is a protein responsible for carrying oxygen throughout your blood stream. Blood hemoglobin levels in humans average at about 14.5g/dL. We are interested in whether a sample of 20 iron deficient individuals have lower blood hemoglobin levels compared to the general population. The average hemoglobin level for our sample is 10.9g/dL, with an estimated population standard deviation of 1.92g/dL. A researcher is looking at whether the time it takes for rats to relearn how to run a maze decreases after they’ve been exposed to the maze more than once. Using 15 rats, he measures how quickly they are able to successfully run a maze at two different times points: once when they are first exposed to the maze, and again after they’ve run the maze three times. A social psychologist is curious about whether social rejection increases aggression in narcissists. He…
A pharmaceutical scientist is testing a drug if it has any effect on helping students improve their performance in an exam. He randomly picks students who will receive the drug and assigned it to group 1. Group 1 (drug group) has a total number of 900 and group 2 (no-drug group) is 1000. Does taking the drug results in changing students’ performance? Mean score in an exam are 9.78 and 15.1 for drug group and no-drug group, respectively. Standard deviation for group 1 is 4.05 and for group 2 is 4.28
A social psychologist recently developed a childhood-memories test that is intended to measure how people recall pleasant and unpleasant experiences from childhood. Scores on the test range from 1 (very unpleasant) to 100 (very pleasant). The psychologist standardized the test with a large group of college students (ages 18-25), and the mean score was p=60. The test was then given to a sample of n=25 individuals who were all between the ages of 40 and 45. The average score for this sample was 64.3 with SS (sum of squares)=600. Note: S?=SS÷df (variance is equal to sum of squares divided by the degrees of freedom). What is your conclusion if you were to test the hypothesis using one- tailed test at a=0.05? O a. Reject the null hypothesis O b. Fail to reject the null hypothesis O c. Accept the null hypothesis O d. None of the above
You are interested in seeing whether emotions impact decision making. You have three groups--a happy group, a sad group, and a neutral group. For the happy group there are 5 participants and the mean risky decision making score 5.0 with a standard deviation of 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. For the 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. What is the degrees of freedom within samples?

In a 2015 study entitled How Undergraduate Students Use Credit Cards, it was reported that undergraduate students have a mean credit card balance higher than $3000. This figure was an all-time high and had increased 42% over the previous five years. Assume that a current study is being conducted to determine if it can be concluded that the mean credit card balance for undergraduate students has continued to increase compared to the report. They want to test to see if the balance for students in 2019 is higher than the balance for students in 2015. See the sample below of undergraduate students in 2015 and different undergraduate students in 2019. Credit Card Increase Students in 2015 Students in 2019 2500 3300 2200 5450 1500 8000 930 2000 5300 870 1150 250 2700 3000 3300 2200 What can we conclude from this t-test? a) Reject the null hypotesis OR Fail to reject the null hypotesis? b) We can conclude that the student balance in 2019 are significatly…
