A mid-sized company has decided to implement an enterprise resource planning(erp) system, and management suspects that many of its employees are concerned about the planned implementation. managers are considering holding informational workshops to help decrease anxiety levels among employees. to determine whether such an approach would be effective, they randomly select 16 employees to participate in a pilot workshop. these employees were given a questionnaire to measure anxiety levels about erp before and after participating in the workshop. to determine if anxiety levels about erp decrease as a result of the workshop, what test should they use?
choices
a. two tailed test of two independent means
b. one tailed test of two proportions
c one tailed paired t test
d one tailed test of two independent means
e two tailed paired test

c one tailed paired t test

One tailed paired t-test is used by the company and this type of paired t-test is used when we want to compare two population means where you have two samples in which observations in one sample can be paired with observations in the other sample in order word , it is been used  when we are interested in the difference between two variables for the same subject

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+%2836%2fx%29%5e2+

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
