In an economy, there are only two goods (Cars and cycles) produced. The data for last three years is given in the below table. Calculate the nominal and real GDP of three years and then find the GDP deflator for all the three years. Find year on year (YoY) inflation for 2018 and 2019. Note: the base year for this economy is given as 2017.

The Graduate Record Examination (GRE) is a standardized test commonly taken by graduate school applicants in the United States. The total score is comprised of three compo- nents: Quantitative Reasoning, Verbal Reasoning, and Analytical Writing. The first two components are scored from 130 - 170. The mean score for Verbal Reasoning section for all test takers was 151 with a standard deviation of 7, and the mean score for the Quantitative Reasoning was 153 with a standard deviation of 7.67. Suppose that both distributions are nearly normal. (a) A student scores 160 on the Verbal Reasoning section and 157 on the Quantitative Reasoning section. Relative to the scores of other students, which section did the student perform better on? (b) Calculate the student’s percentile scores for the two sections. What percent of test takers per- formed better on the Verbal Reasoning section? (c) Computethescoreofastudentwhoscoredinthe80thpercentileontheQuantitativeReasoning section. (d) Compute the score of a student who scored worse than 70% of the test takers on the Verbal Reasoning section.

Dinklage Corp. has 9 million shares of common stock outstanding. The current share price is $81, and the book value per share is $7. The company also has two bond issues outstanding. The first bond issue has a face value of $130 million, a coupon rate of 6 percent, and sells for 92 percent of par. The second issue has a face value of $115 million, a coupon rate of 5 percent, and sells for 103 percent of par. The first issue matures in 24 years, the second in 10 years.

Suppose the most recent dividend was $4.85 and the dividend growth rate is 5.2 percent. Assume that the overall cost of debt is the weighted average of that implied by the two outstanding debt issues. Both bonds make semiannual payments. The tax rate is 22 percent. What is the company’s WACC? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.)

Seasonal affective disorder (SAD) is a type of depression during seasons with less daylight (e.g., winter months). One therapy for SAD is phototherapy, which is increased exposure to light used to improve mood. A researcher tests this therapy by exposing a sample of SAD patients to different intensities of light (low, medium, high) in a light box, either in the morning or at night (these are the times thought to be most effective for light therapy). All participants rated their mood following this therapy on a scale from 1 (poor mood) to 9 (improved mood). The hypothetical results are given in the following table.

(a) Complete the F-table and make a decision to retain or reject the null hypothesis for each hypothesis test. (Round your answers to two decimal places. Assume experimentwise alpha equal to 0.05.)

State the decision for the main effect of the time of day.

Retain the null hypothesis.Reject the null hypothesis.    

State the decision for the main effect of intensity.

Retain the null hypothesis.Reject the null hypothesis.    

State the decision for the interaction effect.

Retain the null hypothesis.Reject the null hypothesis.    

(b) Compute Tukey's HSD to analyze the significant main effect.

The critical value is for each pairwise comparison.

In a genetics experiment, investigators looked at 300 chromosomes of a particular type and counted the number of sister-chromatid exchanges n each. A Poisson model was hypothesized for the distribution of the number of exchanges. Test the fit of a Poisson distribution to the data.
