Dr. Oswald conducts a study examining the relationship between the number of friends one has and the experience of daily stress and life satisfaction. She randomly samples 1,500 elderly men and women in the Memphis, Tennessee, area in the southern United States. Below is a summary of her key findings:

a. Life satisfaction and experience of daily stress:r=-.57, p = .01
b. Number of friends one has and experience of daily stress:r=.09,p>.05
c. Number of friends one has and life satisfaction:r = .36, p = .04

The p > .05 relationship between the number of friends one has and experience of daily stress indicates all of the following EXCEPT

a. Effect size could not be calculated
b. Number of friends and experience of daily stress are unrelated in this sample
c. There is more than a 5% chance the relationship between these two variables is due to chance alone
d. There is not a statistically significant association between the two variables

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.

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0

19479 is the answer ^^
