The prices of a particular variety of rice, per kilo- gram, collected from 48 local stores in the suburban areas of a district vary with a mean of $3 and a standard deviation of $1.6. (a) construct a 95% confidence interval for the mean price. (b) with 95% confidence, what can we assert about the possible size of our error if we estimate the mean price of rice for all the stores in the area as $

step-by-step explanation:

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.

no solution exists the way you wrote the equation.
