The questions below refer to the following situation
A researcher is interested to know if there is a difference in levels of religiosity between different income groups. The researcher administers a religiosity scale to a total of 15 people: 5 "low income" individuals, 5 "middle income" individuals, and 5 "high income" individuals. The means for each group are as follows:
| Group A Low income N=5 | Group B Middle Income N=5 | Group C High Income N=5 | |
| ∑X | 37 | 22 | 43 |
| Mean | 7.4 | 4.4 | 8.6 |
| ∑X2 | 285 | 102 | 381 |
Calculate the mean square between groups (MSbetween). Please round to one decimal place.

Extra Credit (5 pts.) 4. A psychologist is interested in the level of anxiety for adolescents, the middle aged, and seniors. She recruits three samples and gives them a test that measures anxiety, with 1 being low anxiety and 10 being high anxiety. The group data are as follows: Adolescents M1 = 1 n = 5 T =5 SS, = 12 Middle Aged M2 = 5 n = 5 T2 = 25 Seniors M3 = 6 n = 5 T3...

An office manager is interested in the effect anxiety has on the ability of individuals to learn new material. She is also interested in whether the effect of anxiety depends on the difficulty of new material. An experiment is conducted with the design shown below. 45 participants participated in the study (5 per group). Each subject is given 30 minutes to learn the material, after which the subjects are tested to determine the amount learned. Results are shown below (values...

Multiple choice questions 1. Which of the following correctly describes the difference between paired and independent sample data? A) Independent samples operate based on a known o, whereas paired samples may operate with a sample standard deviation. B) Independent samples are used to address the difference between two separate populations, whereas paired samples involve a matched analysis. C) Independent samples incorporate at distribution, whereas paired samples may use the z distribution for approximation. D) Independent samples always have the same...

In West Texas, water is extremely important. The following data represent pH levels in ground water for a random sample of 102 West Texas wells. A pH less than 7 is acidic and a pH above 7 is alkaline. Scanning the data, you can see that water in this region tends to be hard (alkaline). Too high a pH means the water is unusable or needs expensive treatment to make it usable.t These data are also available for download at...

Future Time Orientation and Condom Use for AIDS
Prevention
Background Notes: Researchers administered questionnaires to
male college students taking an introductory psychology course.
Among other things, they measured future time orientation defined
as planning ahead for future events and willingness to delay
gratification. (Sample item: “I believe that a person’s day should
be planned ahead.”) Based on the scores on the future time
orientation scale, they split the male students into two groups –
one low in future orientation and...

The first two questions refer to the following information: Researchers developed an online tool to help ESL students learn prepositions and metaphors. A study measuring academic success in ESL students randomly sampled 100 Spanish speaking ESL students using traditional ESL classes and the new language tool and 81 Portuguese speaking ESL students using traditional ESL classes and the new language tool, and scored them on a common English fluency scale (higher score representing greater degree of fluency). The researchers suspected...
