A researcher wants to see if birds that build larger nests lay larger eggs. Over the course of the year, she collects data by randomly checking different trees in forest preserves across the US. Conduct a hypothesis test at the 5% alpha level to see if large nests have a larger mean nest than other nests. The data is summarized below: Large nests: n=60 mean(gm)=38.2 SD(gm)=4.9

Other nests: n=159 mean(gm) 37.5 SD(gm)=6.4

step-by-step explanation:

answer: 1475

step-by-step explanation:

becuase you have to know what they are asking you

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
