I have two parts. Please explain all parts in detail.

(1). Poor countries have lower capital stock levels compared to wealth countries. Therefore in order for a developement policy to be effective it must target the saving rate.

(2). The prediction of solow growth model are inconsistent with the empirical evidence regarding income convergence.

Let the US economy be characterized by low aggregate output and low and stable inflation. Then, provide a clear definition of the Phillips Curve and consider whether this initial state is consistent with what is shown by this empirical relationship. Conclude by discussing under what conditions expansionary fiscal and monetary could lead to demand-pull inflation. How is economic growth impacted?

The quantitative data set under consideration has roughly a bell-shaped distribution. Apply the empirical rule to answer the following question. A quantitative data set of size 90 has mean 40 and standard deviation 6. Approximately how many observations lie between 22 and 58?

Approximately _____ observations lie between 22 and 58.

Which of the following represents empirical evidence? Group of answer choices

a. A second-hand account of a researcher’s observations

b. A research study without controls identified

c. An experiment that outlines the methods used

d. A review of studies that have been conducted on vaccine safety

e. Research that cannot be repeated because the methodology isn’t clear

Azulene is a beautiful blue hydrocarbon consisting of only C and H atoms. If 0.106 g of the compound is burned in oxygen, 0.364 g of CO₂ and 0.0596 g of H₂O are made. Determine the empirical formula of azulene from this data. [ Hint: First convert the masses of CO₂ and H₂O to moles, then convert the moles found to moles of C to H. ]

The distribution of heights of adult men in the U.S. is approximately normal with mean 69 inches and standard deviation 2.5 inches. Use what you know about the EMPIRICAL RULE to answer the following.

a)Approximately what percent of men are taller than 69 inches?

b)Approximately what percent of men are between 64 and 66.5 inches?

Let the US economy be characterized by low aggregate output and low and stable inflation. Then, provide a clear definition of the Phillips Curve and consider whether this initial state is consistent with what is shown by this empirical relationship. Conclude by discussing under what conditions expansionary fiscal and monetary could lead to demand-pull inflation. How is economic growth impacted?

Grounded theory is a research method that seeks to develop theory that is grounded in data systematically gathered and analyzed. According to Martin and Turner (1986), grounded theory is "an inductive, theory discovery methodology that allows the researcher to develop a theoretical account of the general features of a topic while simultaneously grounding the account in empirical observations or data." Discuss the techniques of grounded theory.
