Researchers conducted an observational study of automobile drivers and their cell phone use by manually observing traffic in heavily congested areas. They would record the amount of time they observed individual drivers on the phone while operating their vehicle in stop and go traffic and the number of accidents on a particular section of highway over the course of a month. The accompanying graph depict the data they recorded, each point represents a 1 mile section of heavily congested roads. From the data, which of these is a potentially valid conclusion? Cell-phone use while driving increases the rate of accidents. Car accidents and cell-phone use have no relationship. The increasing rate of car accidents causes increased Number of car accidents 10- 9- 8- 7- 6- 85- 3- 2- 0 ● 9 6 7 8 Average length of phone calls (minutes) 10

A traditional performance rating benchmark (or guideline) for “normal” effort, or speed, is dealing 52 cardsinto four piles, forming a square with each pile one footapart, in 0.50 minute. Conduct an experiment with one ormore fellow students in which one deals the cards andthe others rate the dealer’s performance, and then compare these subjective ratings with the actual time of thedealer.
The following regression was run using a sample of 587 women living in Kenya. The variable goats is the number of goats the woman owns and grant is whether the woman received $ 500 in cash (in local currency equivalent) two years ago from the charity GiveDirectly, or not. The charity gives grants randomly to poor people in Kenya, of $ 500. goats = 6.42 +0.80 grant R2=0.35 1. What is the estimated coefficient for grant? What does it mean, in words? (Be specific, referring to numbers.) 2. Suppose one woman in the sample, Wangari, did not receive a grant. What is her predicted number of goats? Please do fast ASAP fast
You must identify the relationship between housing price and size. In this experiment, you have collected data from four major cities, namely Birmingham, Manchester, Bristol and Glasgow. What method is suitable for studying this project? Give an explanation.
Scenario: The following model was fitted to data on gas mileage as a function of weight of vehicle and type of vehicle (sport utility vehicle, family sedan, subcompact). Model: MPG = 50 - 0.004WT - 8SUV - 3FS MPG =miles per gallon; WT=weight of vehicle; SUV=sport utility vehicle; FS=family sedan Answer the questions below. 1. Each pound of weight reduces fuel economy by MPG 2. Fuel economy is reduced by MPG for a sport utility vehicle 3. Fuel economy is reduced by MPG for a family sedan 4. For a subcompact car weighing 1000 pounds, what is the predicted fuel economy?
The next 3 questions refer to the following: A housecleaning company receives 36 for each house cleaned. The tab below gives the relation between the number of workers and the number houses that can be cleaned per week. [[[[ Number of], [Workers]], [[Houses], [Cleaned]]], [0, 0], [1, 9], [2, 17], [3, 24], [4, 30], [5, 35], [6,36]] The marginal revenue from the fourth worker is If the company want to maximize profit and hires three workers, the wa rate of a house - cleaner can be no more than If the wage rate of a house - cleaner is 140, the maximum amount of pr the company can earn is
You are studying the effects of smoking by pregnant women on rates of asthma in their children. You collect data on the number of cigarettes smoked per day and whether or not the child developed asthma by the age of two. The data is below: Smoked 1-5 cigarettes per day --- 9.2% developed asthma Smoked 6-10 cigarettes per day --- 10.3% developed asthma Smoked 11-20 cigarettes per day -- 25% developed asthma Smoked 21-40 cigarettes per day --- 34.8% developed asthma Smoked 41-60 cigarettes per day --- 38.4% developed asthma In order to study the relationship between the number of cigarettes smoked by pregnant women per day and the percentage of their children developed asthma by the age of two using statistical knowledge, we convert the above data into the following format and see if we can obtain an adequate fit using linear regression. Average number of cigarettes smoked per day 3 8 Percentage of children developed asthma What is the value of the correlation coefficient? Г 15-5 30.5…

Consider the following hypothetical pooled cross-sectional data of daily COVID-19 cases per 1,000 people during the early two months of the pandemic, from March to April 2020 in Ohio and 5 other neighboring states. The variable April takes value 1 if the recorded cases are from April 2020, and takes value 0 if the recorded cases are from March 2020. The variable lockdown takes value 1 if the state put in place a Stay-at-home order beginning from March 2020, and takes value 0 otherwise. Using the difference-in-differences estimator, assess the impact of the lockdown policy on daily COVID-19 cases. Table 1.
