Listed below are the amounts of mercuryâ (ppm) found in tuna sushi sampled at different stores in a major city. Construct a 98â% confidence interval estimate of the mean amount of mercury in the population. Does it appear that there is too much mercury in tunaâ sushi? 0.56ââ0.79ââ0.10ââ0.94ââ1.36ââ0.54â â0.87

Required:
What is the confidence interval estimate of the population mean muâ?

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

g
