Cola makers test new recipes for loss of sweetness during storage. Trained tasters rate the sweetness before and after storage. Here are the sweetness losses (sweetness before storage minus sweetness after storage) found by 10 tasters for one new cola recipe. 2.1 0.5 0.8 2.1 −0.3 2.3 −1.2 1.3 1.2 2.4 Take the data from these 10 carefully trained tasters as an SRS from a large population of all trained tasters. (a) Use these data to see if there is good evidence that the cola lost sweetness. (Round your answer to three decimal places. Assume a 95% confidence level.)

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

answer: the correct answer is -32
