Note: If the alpha level is not included, set the alpha to .05. Problem 1: The Graded Naming Test (GNT) asks respondents to name objects in a set of 30 black and white drawings in order to detect brain damage. The GNT population norm for adults in England is 20.4. Researchers wondered whether a sample for Canadian adults had different scores from adults in England (Roberts, 2003). If the scores were different, the English norms would not be valid for use in Canada. The mean for 30 Canadian adults was 17.5. Assume that the standard deviation of the adults in England is 3.2. How can we calculate a 95% Confidence Interval (CI) for these data?
Calculate a 95% CI and a 90% CI for this data.
Are the English norms valid for use in Canadian use?
Explain how you know your answer to be true.
How do the two CI’s (95% and 90%) compare to one another?
What is the effect size for these data?
What does this effect size indicate about the meaningfulness of this test for Canadians?
What would you recommend doing to increase the power of this experiment?

Imagine, you are taking a prism to split the sunlight into it's spectrum of colors. You further place a thermometer or temperature probe into each of the three resulting color areas blue, yellow, and red (see schematic).
Which thermometer do you expect to show the highest temperature and why?
Now imagine additionally that you take a fourth thermometer and place it in the area just outside/beyond the red region of your visible spectrum. How would you expect the temperature reading to compare to the other three and why?

Your objective for this project is to do an Internet-based literature search and describe in detail, the methods/processes used by GE to design and develop green products, sustainable production processes, and implement its eco-friendly supply chain.
In 1500 -2500 words, your report should address the following topics:
3a. Describe the general guidelines for designing an environmentally friendly product;
3b. Product design system/methodology used at GE;
3c. provide some examples of GE’s successful green product designs.
4a. Describe the guidelines used by GE to make their operations/production processes eco-friendly;
4b. Give examples of some of the successful green manufacturing processes used at GE.
5a. Suppliers
5b. Transportation & Distribution
6a. Discuss how successful GE has been in achieving its environmental sustainability goals. Provide some supporting statistics.
6b. Describe some of the challenges GE is facing in implementing its sustainability programs in some of the developing countries.
This is a team/group project. The group size is limited to a maximum of three (3) students. Your report should be 1500 – 2500 words (excluding quoted and bibliographic material) long, typewritten, and professional looking. It should be in the APA format and should be written by you in your own words. The “Turnitin” Similarity Index (SI) of your report should be less than 15%.

An education researcher would like to test whether 2nd graders retain or lose knowledge during the summer when they are presumably not in school. She asks nine 2nd graders to take a comprehension test at the end of the school year (May), and then asks those same students to come back after the summer (late August) to retake a different but equivalent test, to see if their level of comprehension has changed. Using the data below, test this hypothesis using an alpha level of .05.

(12 pts) Below is a set of test 1 scores from our Statistics class. 7 of the scores come from females, and 7 come from males. Test the hypothesis that males and females scored differently on our first test, using an alpha level of .05.
