Answer:

a.) The Mean mu Subscript x overbarμxequals= μ

b.) The standard deviation sigma Subscript x overbarσxequals= σ overbar square root of n.

Therefore the sample mean is equal to the population​ mean, but the standard error of the mean on the other hand depends on the sample size.

We notice also, that as n​ increases, sigma x over barσx reduces. Therefore n is inversely proportional to sigma x barσx.

Microeconomics and
gregori [183]

Answer:

Macroeconomics deals with the economy as a whole and so deals with how variables such as government spending and interest rates will affect the entire economy not just single entities.

Microeconomics on the other hand, deals with individual entities in the economy and how various variables and decision making will affect them.

A nation prints more money, causing inflation. MACROECONOMICS.

This affects the entire nation not just single entities so it is macroeconomics.

A local store has a buy one, get one free sale. MICROECONOMICS.

This relates to the actions of a single entity in the economy so falls under microeconomics.

Oil production decreases, and gas prices rise nationwide. MACROECONOMICS.

As this concerns the entire nation, it is therefore under the realm of Macroeconomics.
