really confused on D E F G so please explain what you did to solve them so i can learn how

I. Suppose the United States economy is represented by the following equations: Z = C + I + G C = 300 + 0.9YD T = 1,000 I = 200 YD = Y – T G = 2,000

a. Calculate the equilibrium level of output.

b. After you have calculated equilibrium income, calculate the level of consumption at this level of output. (Hint: Since you know the level of taxes and income, you can easily obtain the level of disposable income to calculate consumption.)

c. Write out the saving function for this economy. Then, calculate the level of saving that occurs at the equilibrium level of output.

d. Now, suppose households decide to increase their autonomous saving by 100. Equivalently, households have decided to cut their autonomous consumption by 100. Calculate the new equilibrium level of output that occurs as a result of the decrease in autonomous consumption of 100. Has this increased desire to save had a positive or negative effect on economic activity? Explain.

e. Based on your analysis in part (d), calculate the level of saving that occurs at this new equilibrium level of output. Compare this level of saving with the level of saving obtained in part (c). What has happened to the level of saving in this economy as a result of the increased desire to save?

f. What is the paradox of saving? Based on your answer in part (e), do you observe the paradox of saving in the short run? Explain.

g. Do you expect to observe the paradox of saving in the long run as well? Why or why not? Explain.

Question text

In the early 1990's, the Oregon Department of Education was looking into the success of their school lunch programs. Critics of the current way funds were being diverted to school food services believed that the low quality of the food being served in the low-income school districts was leading to malnutrition among the students.

The state had already collected growth data for decades throughout Oregon, so they went through their records to look for signs of malnutrition. One metric they used was heights of children in the various school districts. If children did not have proper nutrition from healthy food, they would not grow to their full potential.

The CDC/National Center for Health Statistics put the average height for 12 year old girls in the United States at 59.4 inches, with standard deviation 2.3 inches.

1. Assume that heights are normally distributed. If we randomly selected a 12-year-old female student in a local school, what is the probability that she is no more than 55.4 inches tall?  

The Klamath county school district reported that their female 12-year-old students had a mean height of 58.2 inches out of a sample of 27 students. This a little more than an inch below the population mean for all 12 year old girl's heights.

2. Let's define an unusual event to be one where the probability of it occurring is less than 0.05 (or, equivalently, less than 1 in 20). If we wanted to find out if the school district's mean height was unusually low, what probability should we find?

(Hint: if 58 inches tall is unusually low, then so is 57 inches, and 56 inches.... )

Systolic blood pressure is the amount of pressure that blood exerts on blood vessels while the heart is beating. The mean systolic blood pressure for people in the United States is reported to be 122 millimeters of mercury (mmHg) with a standard deviation of 15 mmHg.

The wellness department of a large corporation is investigating whether the mean systolic blood pressure of its employees is greater than the reported national mean. A random sample of 50 employees will be selected, the systolic blood pressure of each employee in the sample will be measured, and the sample mean will be calculated. Let μ represent the mean systolic blood pressure of all employees at the corporation. Consider the following hypotheses.

H₀: μ=122

H_a: μ>122

a) Assume that σ , the standard deviation of the systolic blood pressure of all employees at the corporation, is 15 mmHg and μ = 122 . Describe the shape, center, and spread of the sampling distribution of x for samples of size 50.

b) Based on the sampling distribution constructed in part a), what interval of values of x would represent sufficient evidence to reject the null hypothesis at the significance level α = .01 ?

c) It was determined that the actual mean systolic blood pressure is 125 mmHg, not the hypothesized value of 122 mmHg, and the standard deviation is 15 mmHg. Using the actual mean of 125 mmHg and the results from part b), determine the probability that the null hypothesis will be rejected?

d) What statistical term is used for the probability calculated in part c)? Explain.

e) Suppose the size of the sample of employees is greater than 50. Would the probability of rejecting the null hypothesis increase, decrease, or remain the same? Explain your reasoning.

Thalidomide is a tranquilizer that was prescribed in the late 1950’s and early 1960’s to pregnant women, with the devastating result of over 12,000 birth defects in 48 countries before it was banned in 1962. (It was never sold in the United States.) Since then, the drug has reappeared as a possible solution to a number of medical problems. The U.S. National Institutes of Health announced on 31 October 1995 the results of a study in 30 hospitals of the effectiveness of thalidomide in healing mouth ulcers in AIDS patients. In the study, which was chaired by Dr. Jeffrey Jacobson of the Bronx Veteran Affairs Medical Center and the Mount Sinai School of Medicine in New York, it was found that 14 out of 23 patients who received thalidomide had their ulcers heal compared to 1 out of 22 patients who received a placebo. As a result of these early trial outcomes, the researchers suspended the trial giving thalidomide to all the patients in the study. THIS IS ALL THE INFO GIVEN.

1. Find a 90% confidence interval for the difference in proportion of healing assuming that both samples are simple random samples and independent of each other.
2. Conduct the appropriate large-sample test of significance. Discuss your results and compare your conclusion with the decision of the researchers.
3. By hand, draw a bar graph depicting the sample proportions of healing. Add a whisker to the top of each bar to denote the standard error of the sample proportion.  DO NOT SUBMIT.
4. Examine the bar graph you produced for part (a). Briefly comment on whether there appears to be a difference in proportions.
5. Conduct the appropriate hypothesis test for a two-by-two contingency table and report the P-values for Fisher’s exact test and the asymptotic chi-square distribution approximation for this test. Compare these results with your answer to part (b) in Exercise 1.
