Part -1:
1. What statistical test was used in Nelson et al., (2010)?
2. Did the authors use the correct statistical test? In other words, what was their rationale for using this test (i.e., were the variables discrete or continuous and was the test appropriate for this type of data?)
3. What was the research question? How did the statistical test address and answer the research question?
4. How did the authors interpret the results of this study?
Part -2:
Review the SPSS output file which reports the results of the correlation to see if there is a correlation between the cost of beer and the number of calories it contains or the cost of beer and the volume of alcohol it contains. Answer the following questions based on your observations of the SPSS output file:
Based on the correlation coefficients (r-values) that were computed and their statistical significance, what conclusions do you draw regarding
1. The researcher's question of correlation between the cost of beer and the number of calories it contains?
2. The researcher's question of correlation between the cost of beer and the volume of alcohol it contains?

A rational expression is a fraction of two polynomials
: A rational expression is a fraction of two polynomials. If you need to add or subtract two rational expressions, how would you do it? Describe, in your own words, the process for finding the Least Common Denominator (LCD) of two rational expre..

Explain white crystalline solid with a melting point
: A student was given a solid for an unknown. Its melting point range was 119-121 degrees Celsius. The student has previously worked with benzoic acid, and has observed that it was a white crystalline solid with a melting point of 122 degree Celsius..

Define the pressure of the atmosphere at sea level
: If the pressure of the atmosphere at sea level, h=0m is 1atm, if T=298K, and if the temperature remains constant and uniform with increasing height, calculate the pressure of air at a height h=1000m and h=10,000m. Do not include any derivation.

Explain concentration of the polycyclic aromatic hydrocarbon
: Calculate the molar concentration of the polycyclic aromatic hydrocarbon (PAH), anthracene (178.23 g/mol), that was found in a well water sample at a concentration of 6.21 ppb. Assume the density of the water is 1.00 mg/mL.
