Given below are the number of successes and sample size for a simple random sample from a population. x 46, n 50, 99% level a. determine the sample proportion b. decide whether using the one-proportion z-interval procedure is appropriate. c. if appropriate, use the one-proportion z-interval procedure to find the confidence interval at the specified confidence level d. if appropriate, find the margin of error for the estimate of p and express the confidence interval in terms of the sample proportion and the margin of error

answer:

d

step-by-step explanation:

50

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
