In an annual report to investors, an investment firm claims that the share price of one of their bond funds had very little variability. the report shows the average price as $18.00 with a variance of 0.24. one of the investors wants to investigate this claim. he takes a random sample of the share prices for 23 days throughout the last year and finds that the standard deviation of the share price is 0.2479. can the investor conclude that the variance of the share price of the bond fund is different than claimed at α=0.05? assume the population is normally distributed.

i'm not entirely sure

step-by-step explanation:

if you ask home depot or lowe's they might be able to you out

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
