You are evaluating a s project that develops AI cars. You dont
have firm-level data,. For this project, you will need take a
top-down valuation approach.
• The revenue of the transportation market is $50 billion dollars
in the year of 2019. Its growth rate in 2020 is -5, in 2021 it is
3%, and goes 0%, 0%, 1%, 1%, 2%,2%,2%,2%,2% which ends in
2030.
• The current revenue share of the AI industry in the
transportation market is 0%. The revenue share will rise in the
year of 2025. It will then stabilize to 40% in the year of
2030.
• 10% is the discount rate in the industry
a. You use linear interpolation to estimate the AI car industry’s
revenue share between 2025 to 2030. In 2024 the market share is 0;
in 2030, the market share is 40%. From 2025 to 2030 (including 2025
and 2030), the increase in the revenue share relative to the
previous year is a constant. What is the AI car industry’s market
share as of 2029?
b. What is the AI car industry’s total revenue in 2030?
c. What is the present value of the AI car industry’s total revenue
from 2020 to 2030? Discount all cash flows back to the year of 2019
(in billions $)?

1. Do you prefer taking test on paper or online? An college instructor believes the tests scores will be the same, on average. This instructor gave identical tests to two randomly sampled groups of 35 students. One group took the test on paper and the other took it online. The results are below. Test whether the test scores are the same at significance level 0.10. Your complete solution should include a comparative boxplot displaying a box for each group, over the same scale.

7. Coke Cola Inc. approach your professor that they have invented a smart energy drink that they believe it can make the students calm and clear about doing statistics. The professor took this drink to the two sections of BUQU1230. One section took the sugar drinks (fake drinks) and the other section took the real drinks.

Assume that the 129 patients in the Patients dataset represent the entire population of interest. If you were interested in age of the patients and took a sample of 25 patients from this population, what is the standard error of the mean? What if you took a sample 64 patients from this population, what is the standard error of the mean? What happens to the standard error of the mean as the sample size increases? If you select a sample of 64 patients, what is the probability that the sample mean is below 75? How to calculate in excel.
