You flip a coin 8 times and record the results using 0 for heads and 1 for tails. You find the variance. Is investigating this sample variance the same as investigating the sampling distribution of the variance?

A. No, the sample only contains 8 coin flips. The sample needs to be much larger

B. Yes, only one person is necessary to flip the coin and find the variance.

C. No, the sampling distribution of the variance is the distribution of the means from all samples, not just one.

D. Yes, the probability of getting heads and the probability of getting tails is the same

hi! i think the answer is 1/2 : )

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
