A researcher is investigating the impact of a firm's capital intensity on its labour productivity using data for the year 2014 for a sample of manufacturing firms from Germany, France, Sweden, Italy and the UK. She has estimated the following model: LP 190 +0.3 × CAPIN - 31.8 × FR + 65.4 × SE + 15.8 × UK - 25.1 × IT where: LP is the firm's labour productivity (measured as turnover per employee, in €000s per employee); CAPIN is the firm's capital intensity (measured as total assets per employee, in €000s per employee); FR is a dummy variable that takes the value 1 if the firm is French and 0 otherwise; SE is a dummy variable that takes the value 1 if the firm is Swedish and 0 otherwise; UK is a dummy variable that takes the value 1 if the firm is British and 0 otherwise; IT is a dummy variable that takes the value 1 if the firm is Italian and 0 otherwise.

Demand for hand sanitizer is surging around the globe as the new coronavirus spreads, prompting retailers to ration supplies and online vendors to hike prices. Sales of hand sanitizers and similar products have swelled across several international markets since the COVID-19 outbreak began in January. The virus, which originated in China, has now spread to more than 60 countries. According to data published Tuesday by market research firm Kantar, U.K. hand sanitizer sales saw a year-on-year increase of 255% in February. Meanwhile, British shoppers were buying 7% more liquid hand soaps and spent 10% more on household cleaners compared to February 2019. (Source: CNBC, 3rd March 2020     ii.

3) You want to study the effects of disposable income, anti-smoking advertising and cigarette prices on the per capita consumption of cigarettes in US. You collect data on these variables across the 51 states over 20 years. You thus have 51x20=1,020 data points. For each state and year, you measure: Y=per capita consumption of cigarette (the fraction of the state population that smoked in that year); Xı=per capital income in the state (in US$); Xx=total expenditure in anti-smoking advertising in that state (in USS); and X3=average cigarette price in the state (in US$). You can then run a model: Y= Bo+Bi*X++ B2*X+ B3*X3+e Explain how you would test that the model is useful in predicting Y: How you would test the alternative hypothesis that you have at least one of the coefficients B1, ß2 or ß3 is different from zero. (That is, the null is that all three coefficients are zero.) Use a significance level a=0.05. (Again, there is no need to “run" the data. Just explain what you would do.…

10.61 The per-store daily customer count (i.e., the mean number of customers in a store in one day) for a nationwide convenience store chain that operates nearly 10,000 stores has been steady, at 900, for some time. To increase the customer count, the chain is considering cutting prices for coffee beverages. The question to be determined is how much to cut prices to increase the daily customer count without reducing the gross margin on coffee sales too much. You decide to carry out an experiment in a sample of 24 stores where customer counts have been running almost exactly at the national average of 900. In 6 of the stores, the price of a small coffee will now be $0.59, in 6 stores the price of a small coffee will now be $0.69, in 6 stores, the price of a small coffee will now be $0.79, and in 6 stores, the price of a small coffee will now be $0.89. After four weeks of selling the coffee at the new price, the daily customer count in the stores was recorded and stored in . At the 0.05…

This is the only information provided for question.   Please answer a) briefly if possible I will upvote Thanks!   Topic - Covid-19 & its impact on housing market   Independent variable (x) : Covid -19   Dependent variable (y) : its impact on housing market   Y tends to decrease when the X rises. The Covid 19 here is the independent variable. When the spread of the virus increased , the income fell which led to the fall in the housing market also. Hence when the X rises , Y tends to fall and when X will fall , Y will rise. Hence the relation formed here will have a negative slope and there is negative correlation between these two variables.   Have you established the correlation coefficient determination of the topic?   a)Does the preciseness of the shift in y as x increases determine the strength of the linear correlation?
