15. An author has written 5 children's books. The number of pages in these books are 64, 65, 73, 74, and 76. a. List all 10 possible SRSS of size n=3, calculate the median number of pages for each sample, and display the sampling distribution of the sample median on a dotplot.

b. Show that the sample median is a biased estimator of the population median for this population.

c. Describe how the variability of the sampling distribution of the sample median would change if the sample size was decreased to n=2.

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.

3/5

step-by-step explanation:

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
