Suppose a professional golfing association requires that the standard deviation of the diameter of a golf ball be less than inch. Determine whether these randomly selected golf balls conform to this requirement at the level of significance. Assume that the population is normally distributed. 1.682 1.679 1.677
1.683 1.681 1.679
1.681 1.682 1.682
1.677 1.681 1.684
What are the correct hypotheses for this test?
Find the sample standard deviation.
Use s to calculate the value of the test statistic.
Use technology to determine the P-value for the test statistic.

i think the answer is b

hello umm i don't understand your question can you explain it more pls

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
