Statistical Analysis
Word count required: 300 words
In the parent involvement study (Deslandes & Bertrand, 2005), the authors reported results for parent involvement at home for ninth-grade students. They say that the statistical analysis of the independent variables and the level of parent involvement at home was F (10, 101) = 6.81,p 6 .001. Discuss the meaning of this statement. What does F stand for? What is 101? What is 6.81? What does p 6 .001 mean?

The spectrum exhibited an absorption band at 260 nm which is attrbutable to benzene, and the absorbance of this band was 0.69. In a reference source, the student found that the molar absorptivity of this benzene band in ethanol
Although an optical rotation of +123° can also be read as -237°, is a specific rotation [a] of +123° the same as one of -237°. If you measured an apparent rotation a of +123°, how could you determine whether or not it is really -237°
