In this problem you will be calculating enthalpy changesforN2 . Do not assume constant values of heat capacity. Use a reference state o fT = 25 ̊C and 1 atm pressureto set H = 0 kJ/mol.

a.What is the change in enthalpy thereference state to400 ̊C?

b.What is the change in enthalpy from 800 ̊C to 400 ̊C? In addition, what is the value for enthalpyat 800 ̊C?

c.If the reference state for N2was changed to 100 ̊C, would your answer for part (b) change? If so, what would the change be?

1. Your boastful roommate claims that fans for the Chicago Bears (the city’s football team) are simply more intelligent than the average person. With your newly-developed statistical tools, you decide to put this hypothesis to the test. You know that the standard intelligence quotient (IQ) score has a population mean of 100 with a standard deviation of 15. You find that a random sample of 121 Bears fans has an average IQ score of 103. Use this evidence to test your roommate’s argument that Bears fans are more intelligent than the general population.

1. (1 point) In symbols or words, what is the null hypothesis for this test? _____________

2. (1 point) In symbols or words, what is the alternative hypothesis for this test? _______

3. (1 point) Is this a one-sided or two-sided test? How do you know? _________________

4. (1 point) Will you use a z-test or a t-test in this situation? Why? ___________________

5. (1 point) What is the critical value of the test statistic given an α level of 0.05? ______

6. (2 points) What is the value of the test statistic calculated from the sample results?

7. (2 points) What is your decision about the null hypothesis, and what does this indicate about the intelligence of Bears fans relative to the average person?________________

8. (3 points) Would your decision be different if you used an alpha level of .01? Explain.

A business needs to know whether customers of different genders have specific favourite colours. Using the following information, develop a contingency table test. Male: 10 blue, 18 red, 22 black Female: 25 blue, 11 red, 14 black At at 0.05 level of significance, use formal hypothesis test to determine whether colour preference of a customer depends on gender.

(Q001) Glucose-6-phosphate dehydrogenase deficiency (G6PD deficiency) is an inherited disorder where either the body has less of the G6PD enzyme than normal or the available G6PD is not functioning correctly. This deficiency affects red blood cell function and may result in anemia (the destruction of red blood cells) when people with the condition have infections, are taking certain medications, or eat certain foods. People with G6PD deficiency may have some protection from malaria because their abnormal red blood cells interfere with the reproduction of the malaria parasite in their bodies.

Consider the prevalence of G6PD deficiency estimated by the World Health Organization (WHO) as shown in the map on p. 247 of your lab manual. Compare the distribution of G6PD deficiency with the distributions of the sickle-cell trait and malaria shown in Figure 8.9 on p. 238 of your lab manual. What similarities between these distributions do you notice? What differences do you notice?

(Q002) Why might these similarities and differences exist? Be sure to consider the evolutionary context (including the natural environment, cultural practices, and interbreeding).
