Suppose you are working as a manager of an organic grocery store and want to analyze how
income affects grocery spending.
In the dataset, grocery_spending measures the amount spent on groceries in dollars,
and income represents individual income, also measured in dollars. The following
regression results present estimates from two different specifications.

Both the level-level and level-log regression models presented above use the same number of observations. What does this suggest about the variables used in each model?
Calculate the R-squared value for the missing section. (Round totwo decimal places. You do not need to show your work.) Based on this answer, which model specification provides a better fit to the data? Why?
On the level-level model specification, what is the null hypothesiswe would like to reject? Briefly describe the null hypothesis in words.

They want to run a simple linear regression, where enroll is an indicator variable equal to 1 if a student enrolls at UCSC, and 0 if the student applied but did not enroll. distance measures the distance in miles. They tried to run a regression as follows. enroll = B + B₁ distance + u 0 1 However, the reg command suddenly stopped working, and they were only able to calculate summary statistics. They found that enroll = 0.23, distance = 54, s = =-82, s = 91, and s = 0.23 distance,enroll distance enroll Find B and B Round to two decimal places. (Just enter the number.

Ensure that you carefully explain/justify the reasoning behind the development of your model. NOTES: start with the models and theories discussed in this course. You should carefully examine each model. Based on this, you should be able to identify what aspects you think are relevant/necessary for the Caribbean context and which are not. Once you have the aspects of the model you deem relevant, you need to organise them into the “ideal” model of Caribbean economic development. This should include model objectives and assumptions that describe the setting and the behaviour of the economic agents, model inputs, etc. You will now need to analyse your new model.
