Chapter 2, Problem 49SE
The term Beta refers to a measure of a stock’s price volatility relative to the stock market as a whole. A Beta of 1 means the stock’s price moves exactly with the market. A Beta of 1.6 means the stock’s price would increase by 1.6% for an increase of 1% in the stock
market. A larger Beta means the stock price is more volatile. The Betas for the stocks of the companies that make up the Dow Jones Industrial Average are shown in Table 2.17 (Yahoo Finance, November 2014).
- a. Construct a frequency distribution and percent frequency distribution.
- b. Construct a histogram.
- c. Comment on the shape of the distribution.
- d. Which stock has the highest Beta? Which has the lowest Beta?

Cryptocurrencies have rapidly become an important alternative to traditional currencies for many types of transactions. Etherium, one of the most prominent cryptocurrencies, has rapidly appreciated in value. Daily Etherium trading information for the first 332 days of 2021.
It includes the following variables:
Date
Day – Day of the year, used to assess trend over time
Volume (US $) – Daily trading volume
Opening Price (US $) – Opening price for daily trading
Price Change (US $) – Daily change in price from opening to close
1. Determine the sample correlation coefficient, r, between Volume and Price Change. Test the alternative hypothesis that Volume has a linear relationship to Price Change. Specifically, what are the test statistic and the p-value for that test statistic? For α = .05, what do you conclude about the relationship between the variables? (reminder: the T.DIST.2T function requires input of a positive test statistic)
Please give correct answer ASAP.
Turbid water is muddy or cloudy water. Sunlight is necessary for most life forms; thus turbid water is considered a threat to wetland ecosystems. Passive filtration systems
are commonly used to reduce turbidity in wetlands. Suspended solids are measured in mg/l. Is there a relation between input and output turbidity for a passive filtration
system and, if so, is it statistically significant? At a wetlands environment in Illinois, the inlet and outlet turbidity of a passive filtration system have been measured. A
random sample of measurements are shown below. (Reference: EPA Wetland Case Studies.)

In your data you have a variable, "number of reported violations," that records how many violations each factory has had. When the number of reported violations goes from 9 to 10, the probability of being inspected jumps from 20% to 60%. Average pollution levels decrease from 600k metric tons of CO2 to 450k metric tons going from 9 to 10 violations as well. Calculate the fuzzy regression discontinuity estimate of the effect of inspections on pollution output.arrow_forward
