Find a 90% confidence interval for the population standard deviation for the weights of men if a sample of 14 randomly selected men have a sample mean of 156.9 pounds and a sample standard deviation of 11.1 pounds. Assume that the population has a normal distribution.

Who do you think got the better deal in the Compromise of 1850, the North or the South? Why?

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
