Statistics: A group of young businesswomen wish to open a high fashion boutique in a vacant store. The business women believe that the average income of households in the area is at least $27,000. Data from a random sample of 9 households is show below. Using a hypothesis test, test to determine if average income in the area is at least $27,000. The level of significance is .10. State H(o) and Ha, critical value, test statistic, and your decision,

t= 1/3.

hope this .

step-by-step explanation:

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
