Sign test for paired datas conceptions

My professor said for the sign test we are not testing median_x=median_y

and the difference median(x-y) is not equal to median_x-median_y

I am so confused.

Please tell me are we testing if two samples have the same median??? Please explain the conception and give out some examples

follow the comment as well

Intermediate Accounting II: Problem 15-A My professor said that for the retained earnings section of the Stockholders' Equity portion, we need to include the net income of $130,000 to our retained earnings balance. That would give us retained earnings of $445,900 and subsequently a total stockholders' equity of $844,600. Is that correct? My professor has been known to have a slip up from time to time...

We had an example in class about using a sign test. We are supposed to find the b value by using the binomial table. b(alpha,n,1/2) which for this problem equals b(.05,10,1/2). When you use the binomial table, the b(.05,10,1/2) = 8. How do you use the binomial table to get 8 for the b value?

We use a paired-samples t test when we have two samples, and the same participants are in both samples; to conduct the test, we calculate a difference score for every individual in the study. Discuss what areas in psychology would benefit from using a paired-sample t test to better understand that phenomena. For example, when measuring intelligence, we could develop an intervention to help improve intelligence, and the compare before and after scores for each participant. I asked this question...

We would like to test H_0: μ x ≥ μ y in a paired setting. The sample data shows the sample mean of X is larger than the sample mean of Y. And the sample covariance satisfies s_xy >0.
