Amedical website states that 40% of u. s. adults are registered organ donors. a researcher believes that the proportion is too high and wants to test to see if it is lower. she selects a random sample of 200 adults and finds that 74 of them are registered organ donors. perform the hypothesis test at the 0.05 level. compute the p-value and state a conclusion.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

combine all like terms then its just a 2 step equation

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
