Answer correctly and read the questions corretly, this is all one quesiton if done correclty and organized I will write a very nice review about you!
As an admissions counselor, I am interested in understanding whether or not there is a difference in stress levels not only between different majors but also between different classes (Freshman v. Seniors). I gather the following data from students from three majors (Psychology, Chemistry, and Engineering), that are in their freshmen or senior years and ask them about their stress levels (scale of 1-10, with lower numbers meaning less stress). Using the data below, test whether there are effects of class, major, or an interaction between them at an alpha of 0.05. Psychology Chemistry Engineering Freshmen 3, 4, 4, 2, 4 4, 5, 7, 8, 4 5, 7, 7, 8, 5 Senior 4, 5, 5, 3, 5 8, 5, 6, 7, 7 9, 9, 8, 7, 9 Complete the ANOVA summary table below: Source SS df MS (variance) F MAJOR CLASS MAJOR*CLASS ERROR/RESIDUAL Nothing here TOTAL Nothing here Nothing here What can we conclude?…
In a study assessing helping behavior among college students on their way to class, you recruit 10 students. You tell some participants that they are late for class and need to rush. You tell others they are right on time. Finally, you tell others they have lots of time before class. As they walk across campus, they come across a man (actually a confederate) who appears to need help. You measure the extent to which the participant noticed that the confederate needed help (1 = did not notice to 9 = really noticed). What is the acceptable level of risk? P >.05 p <.05 P = .05 P <.1
Researchers wondered whether the size of a person's brain was related to the individual's mental capacity. They selected a sample of 3 females and 3 males and measured their MRI counts and IQ scores. The data is reported on the right. Females Males MRI IQ MRI 10 866,664 132 965,355 132 790,620 135 1,001,121 141 856,473 141 1,079,550 135 O Treat the MRI count as the explanatory variable. Compute the linear correlation coefficient between MRI count and IQ for both the males and the females. Do you believe that MRI count and IQ are linearly related? The linear correlation coefficient for females is. The linear correlation coefficient for males is. (Round to three decimal places as needed.) Are MRI count and IQ linearly related? linear The linear correlation coefficient for females is close to ▼so relation exists between MRI count and IQ for females. The linear correlation coefficient for linear relation exists between MRI count and IQ males is close to for males. SO
A middle school wanted to examine if students' sense of school belongingness increased after participating in a two-week after-school program. Thirty students were selected to participate in the after-school program. Prior to completing the program, students completed a measure of school belonging. At the end of the two-week program, students completed another measure of school belongingness. Students' scores before and after the program were then compared. What is the DV? O 30 participants O (before and after) the after school program O Sense of school belonging O the middle school
Empathy among police officers influences how they interact with citizens and the likelihood that they receive complaints. Gender differences in levels of empathy in the general population are not large but male and female officers have been shown to have different interaction styles with the public; this may be due to the different empathy levels. After sampling officers and measuring their levels of empathy you find the following data. Males Females n = 6 n = 9 M = 31 M = 45 SS = 490 SS = 680 If you were going to make gender comparisons like this, which option would be the correct choice? Write A or B in the box. [a] Option A. Independent-measures t-test Option B. Repeated-measures t-test
A report summarizing scores for students on a verbal aptitude test x and a math aptitude test y gives the following results: x = 480, sx = 80, y = 500, sy = 120, r = 0.6.
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)
Need help with this question. Thank you :)
. Is using meditation to relax and clear the mind a natural way to treat insomnia? Design an experiment to investigate this question. Assume that you have 20 individuals who suffer from insomnia available to participate in the study. At the end of two months, you will ask subjects to rate their sleep quality.
The Bureau of Labor Statistics reports that the official unemployment rate for Black people was 10.4% and 4.7% for White people in February 2015. Select all correct answers for this question. O The samples of white and black people are independent. The explanatory variable is the unemployment rate. The response variable is the unemployment rate. The response variable is race.

As they walk across campus, they come across a man (actually a confederate) who appears to need help. You measure the extent to which the participant noticed that the confederate needed help (1 = did not notice to 9 = really noticed). Which hypothesis test would you calculate?
