A recent study on crime rates examines whether crime depends on sunshine. A researcher hypothesizes that sunshine makes people h

Answer and Explanation:

R-square measures whether the variation exists or how much dependence the independent variables on the dependent variables.

R2 = .45 which is quite low. This shows that there is not much variation. In order to increase the R2 the researcher can add more independent variables.

The below part is taken from the internet as the question was incomplete:

Sunny days = 0.5

Intercept = 2.1

The slope shows a positive relationship (direct relationship) with the dependent variable which is crime dependency.

Sunny days is the independent variable.

Intercept is also positive whereas there is significance in the p value which helps in concluding that we will reject the null hypothesis.

ivann1987 [24]

Answer:

Having a good business idea and market research would make it crystal clear whether or not the project is viable or not. The first thing is that Jean must consider is that he must analze whether the project is financially viable or not. Once we are sure that the return is above the market average thereafter then Jean must consider writing the business proposal.

In business proposal Jean must present his innovation, market research, customer segments, entrepreneur ecosystem in which the business would operate. The marketing strategy, sales forecasting on well researched market research which provides solid grounds for forecasting, future targets, etc. So these all things must be considered while writing. I have prepared a business proposal and worked as a market researcher for that business proposal, traveled 300km for gathering market research. Paper work is nothing in startup. Everything is your market research, understanding your customers, competitors and costs that are associated with the products that we are going to offer.

I will also like to tell that commitment brings money. If you are committed to do a particular thing then be committed but you must analyze the situation first (market research, investment appraisal). Funds are limitless to committed poeples. US startup loans, accelerators programs, etc. There are millions of sources of finance options. We are not in 19 hundred, we are in a modern world and we can arrange money for an attractive investment.

The marginal impact of overall medical spending on health status is ________in the United States. The marginal impact of prevent
Mumz [18]

Answer:

C - larger; smaller

Explanation:

Marginal effects usually determine the change in a dependent variable (overall medical spending) based on a change in another variable that affects the dependent one (Spending on preventative care), all things remaining the same. If spending on preventative care is high, the overall medical bill should be low, assuming treatment costs, labor costs of health workers and all other factors are constant. If preventative care spending is low, the overall medical spending will be high.

The marginal effects of overall medical spending on health status is larger in the US. The marginal effects of preventative care spending on health is likely smaller than for overall spending.
