Suppose that a population parameter is 0.3 and many samples are taken from the population. If the size of each sample is 40, what is the standard
error of the distribution of sample proportions?

b. 2

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5

=2

the answer is 13/48
