A school psychologist wishes to study the influence of three new curricula plans on the history achievement of junior high school students. Although the groups of students were selected on a fairly random basis, the psychologist has learned that there is considerable disparity among the groups with respect to verbal aptitude.

You are working on a manufacturing process that should produce products that have a diameter of 3/4 of an inch. You take a random sample of 35 products and find the diameter to be 13/16 of an inch with a standard deviation of 5/32 of an inch. 1. Considering a t% level of significance, what can you state statistically about the process? Please include a null hypothesis, an alternative hypothesis, and use an appropriate test statistic (I.e. Zstat or Tstat).

A certain golf club manufacturer advertises that its new driver (the club you use to hit golf balls off the tee) will increase the distance that golfers achieve relative to their current driver. We decide to test this claim by having 15 golfers hit a drive using the new driver, and then hit one using their current driver. Here are the data for 15 people, with yardages using both clubs:
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | |
| New | 247 | 259 | 248 | 275 | 282 | 307 | 288 | 215 | 221 | 260 | 292 | 198 | 240 | 304 | 295 |
| Current | 240 | 254 | 238 | 268 | 275 | 301 | 292 | 197 | 203 | 262 | 281 | 189 | 225 | 297 | 274 |
a) Show a side-by-side boxplot of the driving distances for the current and new drivers as well as the difference between new and current drivers (a total of three boxplots, side-by-side. Conduct a paired t-test to test whether the new driver produces longer drives, on average, when compared to the current driver using .05 as the probability of a Type 1 error. State your hypotheses, and be sure to check the conditions for your test. State the P-value of your test. (Feel free to use R in showing your work - and show your commands and output if using R.)
b) By using a 95% confidence interval, estimate the true difference in length produced by the new driver relative to the current one, and explain what this confidence interval means in context of this problem. (Feel free to use R in showing your work - and show your commands and output if using R.)

Thalassemia is a genetic disorder where affected individuals have red blood cells that produce too much iron. This disease is inherited as an autosomal recessive (tt). However, heterozygous individuals (carriers= Tt) may have some immunity to malaria (similar to sickle cell anaemia). Human blood samples are obtained from a Mediterranean population of 100 people where malaria is endemic. Of these, 50 people are found to be carriers (Tt), and additional 3 people have thalassemia (tt). Use these observed results to explain if heterozygous individuals have partial immunity to malaria?

Part 5
Assume an economy is in recession and the government is considering using fiscal stimulus measures to boost spending, production and employment.
a) Using the IS-LM curve diagram, illustrate the crowding out problem that could occur as a result of increased government spending. Make sure to clearly indicate the new equilibrium position including showing how both the interest rate and level of Y change.
b) Explain how 'crowding out' can harm productivity growth.
c) Explain how the 'crowding out' problem associated with increased government spending can be avoided. In your answer identify any additional policy that is needed.
At the end of your answer to Part 5 state the combined word count for sub-parts b and c. Your answer to Part 5 sub-part b and c should not exceed 150 words.
(3 marks for sub-part a, 1.5 marks each for sub-parts b and c plus 0.25 marks for satisfying the word count requirements - Part 5 worth 6.25 marks)
Part 6
The recent Federal Budget featured significant tax cuts to help stimulate the Australian economy which is currently in recession. Shortly after the announcing the budget, Treasurer Josh Frydenberg announced: “These tax cuts will put more money into people’s pockets and that money will be spent across the economy and that money will help create jobs.”
With reference to what you have learned about fiscal policy as part of this course, and in light of the current economic situation in Australia discuss the logic behind the Treasures statement. In your answer identify whether or not, or to what extent you agree with the Treasurer and explain why. In your answer draw on relevant evidence and examples as necessary to support your answer.
At the end of your answer to Part 6 state the word count. Your answer to Part 6 should not exceed 200 words.
(5 marks plus 0.25 marks for satisfying the word count requirements - Part 6 worth 5.25 marks)

A piston-cylinder device initially has a volume of 1.5 m3 containing steam at 300 kPa absolute and 150 oC. It is then heated so it expands at constant pressure until it reaches a temperature of 400 oC.
Draw a diagram of the device showing system boundary and flows of energy. What boundary work is done by the cylinder, in kJ, during the expansion? State your assumptions.
1. What is the mass of steam in the piston-cylinder?
2. How much heat is added to the cylinder, in kJ, during the expansion? State your assumptions.
3. Assuming there are no irreversibilities during the expansion; S.GEN=0, does the entropy of the steam decrease, remain constant, or increase during the expansion? Explain your answer.
