Two researchers, Jaime and Mariya, are each constructing confidence intervals for the proportion of a population who is left-handed. They find the point estimate is 0.25. Each independently constructed a confidence interval based on the point estimate, but Jaime's interval has a lower bound of 0.243 and an upper bound of 0.257, while Mariya's interval has a lower bound of 0.183 and an upper bound of 0.271. Which interval is wrong? Why?

i understand 100% 10/10 hit or miss?

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

b.
