Conducting a z-Test Psychological Statistics Module 2: Assignment 2 Argosy University Gemini Dickerson 3/12/14 A film was shown to 36 students to see if the attitudes of students toward the mentally ill would change. The results of the class of 36 that watched the film had a score of 70. The results of the class that did not watch the film had a score of 75. The standard deviation is 12. When the alpha is set to 0.05. .05 is a mid-probability. It means we’re using to reduce the likelihood

EFT4 Task 5 5th and 6th graders will be introduced to the concept of surface area of a cube. When doing so I would first begin by connecting previous learning with the new concept. These previous concepts are the prerequisite skills necessary to complete this task. Students will need to know how to compute for surface area. Some experience with using the equation (L x W) to compute for surface area is also helpful when advancing to surface area of a cube. Secure understanding of multiplication facts

How do shapes affect structure? From the Roman arches to the triangular Great pyramids to religious domes and the variety of quadrilaterals found on steel-frame buildings of the 20th century‚ architecture is largely predicated on shapes. The mathematical attributes of shapes are necessary to the design of any standing structure. Arch The Romans first used arches around 273 B.C. Arches served as entrances for large‚ outdoor public spaces. Today‚ arches are found on porches‚ doorways and
