Aleasing firm claims that the mean number of miles driven annually, u , in its leased cars is less than 12800 miles. a random sample of 50 cars leased from this firm had a mean of 12499 annual miles driven. it is known that the population standard deviation of the number of miles driven in cars from this firm is 3140 miles. is there support for the firm's claim at the 0.05 level of significance?

for 0.05 level of significance p value is greater than so it cant not reject

Step-by-step explanation:

given data

mean = 12499 miles

sample n = 50

standard deviation = 3140 miles

μ = 12800 miles

to find out

Is there support for claim 0.05 level significance

solution

we find here first standard statistic test for z

z =  ( mean - μ)  / ( SD × √n )    1

put here value

z = ( 12499 - 12800)  / ( 3140 / √50 )

z = -0.67783

and we can find from table

P value for z is -0.67783 is 0.2489

so for 0.05 level of significance p value is greater than so it cant not reject

step-by-step explanation: the declaration of the rights of man and of the citizen (french: déclaration des droits de l'homme et du citoyen de 1789), set by france's national constituent assembly in 1789, is a human civil rights document from the french revolution.[1]

the declaration was drafted by the abbé sieyès and the marquis de lafayette, in consultation with thomas jefferson.[2] influenced by the doctrine of "natural right", the rights of man are held to be universal: valid at all times and in every place, pertaining to human nature itself. it became the basis for a nation of free individuals protected equally by the law. it is included in the beginning of the constitutions of both the fourth french republic (1946) and fifth republic (1958) and is still current. inspired by the enlightenment philosophers, the declaration was a core statement of the values of the french revolution and had a major impact on the development of freedom and democracy in europe and worldwide.[3]

the 1789 declaration, together with the 1215 magna carta, the 1689 english bill of rights (1689), the 1776 united states declaration of independence, and the 1789 united states bill of rights, inspired in large part the 1948 united nations universal declaration of human rights
