consider the two functions:
f(x, a) =70- 5xa & g(x) = 30 +4x
a) find the x value of the point where the two equations intersect (in terms of the variable a)
b) find the value of the functions at the point where the two equations intersect (in terms of the variable a).
c) take the partial derivate of f with respect to x, \partial f / \partial x, and with respect to a, \partial f / \partial a
d) what are the values of these derivatives , when x= 3 and a=2, which can be written as \partialf /\partialx (3,2) and \partial f /\partiala (3,2)
e) next caculate these two numbers:
\upsilon1 = (\partialf /\partialx ( 3,2)) 3 / f (3,2)
\upsilon2 = (\partialf /\partiala ( 3,2)) 2 / f (3,2)
f) finally write out these equations in term of a and x and simplify,
\upsilon1 = (\partialf /\partialx ( x, a)) x / f (x, a)
\upsilon2 = (\partialf /\partialx ( x, a)) a / f (x, a)

Powerful women's group has claimed that men and women differ in attitudes about sexual discrimination. a group of 50 men (group 1) and 40 women (group 2) were asked if they thought sexual discrimination is a problem in the united states. of those sampled, 11 of the men and 19 of the women did believe that sexual discrimination is a problem. if the p-value turns out to be 0.035 (which is not the real value in this data set), then at = 0.05, you should fail to reject h0. at = 0.04, you should reject h0. at = 0.03, you should reject h0. none of these would be a correct statement.
