Correlation analysis results suggest a moderate negative relationship between price and floor, a moderate positive relationship between price and distance, and strong positive relationship between price and view. End and furnish have weak and negative relationships with price. Appendix 2 shows the results. Regression analysis for the relationship between price and the other variables, as independent variables, identifies a significant relationship (p=2.42*10-23, F= 39.69) and the model is reliable. Appendix 3 shows the results. View of the beach is significant (p= 4.3*10-20, t= 1.92) and apartments with view of the sea have higher prices (mean= 22021.3) than those without view (mean= 18105). Appendix 4 shows the results. Apartments with their views partially blocked have lower prices (mean=18714.3) than those that are not blocked (mean= 20177.7) but the difference is not significant (p= 0.26, t= 1.97). Appendix 5 shows the results. Price difference between apartments with furniture and those without is however minimal (means= 20104.2, 20141.6 respectively) and the difference is not significant (p= 0.99, t= 1.97). Appendix 6 shows the results. Appendix 7 shows table of coefficients for regression analysis results for the relationship between price and the independent variables. The results shows that only furniture is not significant to price (p= 0.24, t= 1.19) and the following is the model. The model omits furniture because it is not significant. It is important to note that while end is not significant when considered separately, it is significant when investigated with other variables and interaction effects could explain this. Coefficients of the regression analysis

Radiography Skills - Essay Example In addition, this distance is important in bringing sharper images and details of the delicate structures of the lungs. While doing the radiographic image of the body chest, an oblique sternum in the LAO position is not preferred. This is because oblique sternum position is only about 15o and opens the body joint at a very close angle to with the image receptor and also projects the sternum onto the right as opposed to left positioning recommended. Oblique sternum positioning of the LOA therefore fails to demonstrate the best axillary portions of the body ribs and instead, an AP oblique projection is preferred (Ramlaul, 2010). While doing abdominal radiography, the filming must include diaphragms as it demonstrates fluid and free air levels. Chest must be included in the acute abdomen examination because it has muscles that are of great radiologic significance. Different chest X-rays imaging are preferred for expiration and inspiration. In particular, for an inspiration, posteroanterior (PA), a form of portable chest x-ray is preferred as it exposes the crowded inspiration organs, while AP form of chest X-ray is commonly used for expiration (Ramlaul,
