DuToit , Hansen, and Osborne measured the diameters of some no. 10machine screws with two different calipers(digital and Vernier scale).Part of their data is recorded here. Given in the small frequency table are the measurements obtained on 50 screws by one of the students using the digital calipers Diameter (mm) Frequency
4.52 1
4.66 4

In the context of the machine screw diameter study of exercise 4 of section 6.1, suppose that the nominal diameter of such screws is 4.70 mm. Use the five-step significance-testing format and assess the strength of the evidence provided by the data that the long-run mean measured diameter differs from nominal. (you will want to begin with HsubO mu=4.70 mm and use HsubA mu does not equal 4.70mm)

step-by-step explanation:

is their an equation anywhere i can take a   look at it and see if i am right.

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
