On March 10, 2020, nine NBA games were played. The average number of points scored in those games was 226, with a sample variance of 122.5. Assuming that the underlying distribution of the data is normal and that these observations are independent and identically distributed, construct a 90% confidence interval for the true mean number of points of an NBA game.

step-by-step explanation:

divided 3/4 and 6

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
