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.

Our current system of federal income tax has seven tax brackets, starting at 10% for income up to about $10k for a single person, and caps out at 37% for income above $500k. (We’ll ignore all the loopholes.) Suppose that instead of doing things this way, we tried to create a tax in which everyone pays the amount of money that would reduce the utility of their pre-tax income by (say) 10%. What would happen to the amount that people pay, and why? Explain your answer both for the case of someone who is currently in the lowest income bracket as well as someone in the highest. (You don’t need to use exact numbers.)

There has been a lot of controversy surrounding the use of genetically modified organisms (GMO) in food production. Your assignment is to take a side on this controversy. What evidence is in support of the side you choose? I want to talk about the negative side of it! about 500words. You will need to provide at least five (5) credible sources to support your argument.. Could someone help me answer this and put the 5 reference sites as well?

Based on the data above, calculate the slope of the line of the absorbance vs relative concentration for each for the four data sets (Part III in your lab manual).
Let:
αHMR
IA equal the slope for solutions A0-A3 at 425
mm
αMR-
IB equal the slope for solutions B0-B3 at 425
mm
αHMR
IIA equal the slope for solutions A0-A3 at
520 mm
αMR-
IIB equal the slope for solutions B0-B3 at
520 mm
These α's are the respective Beer's Law constants for HMR and MR- at the 2 wavelengths. Enter below the α's that you determined from your Excel graphs

Vapor Pressure and Heat of Vaporization
a. The vapor pressure of acetone at 20° C is 185.5 mm Hg, and the vapor pressure of water at this same temperature is 17.5 mm Hg. Predict which of the two liquids will have a higher normal boiling point. Use a molecular point of view to explain your prediction.
b. Use data from the table below and make a graph of the lnP versus the reciprocal of absolute temperature. Use the slope from a linear regression fit and determine the heat of vaporization. It should be about +42.8 kJ per mole.
| P in mm Hg | 1 | 10 | 40 | 100 | 400 |
| T in °C | -31.3 | -2.3 | 19.0 | 34.9 | 63.5 |
