Management science department have conducted an IQ test to evaluate the level of students. The department divide the students in two independent groups. The results of both groups are as follow. Formulate a hypothesis to test the difference between two groups at α=0.01. Group I: 129, 132, 115, 110, 117, 121, 112, 120, 116.
Group II: 135, 141, 138, 140, 139, 142, 137, 134, 136.
First you are suppose to perform the test for equality of variances.

6^2 or 36

step-by-step explanation:

6000n

6×1000n

6×10^3 n

so we need 6n need to be a perfect cube

so n has to be 6^2 so that 6n is 6^3

what i'm saying is if you let n be 6^2 you have 6^3×10^3 or 60^3 which is a perfect cube

is there a graph

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
