The health of the bear population in yellowstone national park is monitored by periodic measurements taken from anesthetized bears. a sample of 54 bears has a mean weight of 182.9 lbs and a standard deviation of 121.8 lb. use 0.10 level of significance to test the claim that the population mean of all such bear weights is less than 200 lb., also, give the p_ value.

i'm a sophomore in connections, i'd recommend checking on jishka.com they have a large range of questions and answers from our school.

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
