The ages of a group of 147 randomly selected adult females have a standard deviation of 17.5 years. assume that the ages of female statistics students have less variation than ages of females in the general population, so let sigmaequals17.5 years for the sample size calculation. how many female statistics student ages must be obtained in order to estimate the mean age of all female statistics students? assume that we want 90% confidence that the sample mean is within one-half year of the population mean. does it seem reasonable to assume that the ages of female statistics students have less variation than ages of females in the general population?

Alright so, i got your question but not the rights listed below. can you tell me them? ( somebody don't delete this i'm just asking ; -; )

Aunitary state is a form of state where power is concentrated and there is a single center of power that extends its actions throughout the territory of the respective state. this, through its agents and local authorities, delegates of that same central power, and in its majority; it can count on a single legislating apparatus; except for certain exceptions, which legislate for the entire country; a judicial power, which applies the current law to the entire territory of the state and within which a supreme court of justice is established, which has jurisdiction at the national level; a single executive power, that is conformed by all the governors (president, governors, mayors, etc.); and a single political constitution, which governs all the territory and to which all the authorities and inhabitants of the state are subject.a confederation (from the latin: confœderatĭo) consists of the union of states that retain their sovereignty and are governed by certain common laws. initially there was talk of "confederation" in the case of alliances, for this reason the word "confederation" is still used in non-governmental civil society institutions. for this reason, the term confederation is also used to describe any type of organization that combines the authority derived from other semi-autonomous entities. in this case, sports confederations can be cited as some examples. however, the word confederation takes much more relevance when it comes to some permanent alliance of states or some association or association of states.characteristics of a federal government system

  a) written constitution. also known as magna carta and a necessity of the democracies that form federations to regulate the principles by which the government will be governed, because if they had to act without a body of specific laws would produce confrontations.

b) territorial division. federalism is constituted by the division of powers on the geographical basis of each territory.

c) decentralization. in a federal system there is both a central government and units of government lower than the central one, each making decisions regarding the provision of certain public services in their respective geographical jurisdictions.

d) supreme court of justice. to counteract the rigidity of the written constitution, judicial action is required to interpret said constitution and necessary changes can be made.

D, because civic virtue is basically doing what’s morally good.
