Company is deciding whether to renew its ad buy with a local tv station. it will renew the ad if a 2-sided hypothesis test at the 10% level concludes that more than 19% of the local residents remember the ad. they decide to test this by contacting 284 randomly selected local residents. sixty-four (64) of the 284 remember the ad. a. conduct by hand the requested hypothesis test based on this sample using the normal approximation. (that is, write the hypotheses, compute the test statistic by hand then use minitab (probability distribution plot or calculator) to get the p-value . remember, these by hand calculations do not need to be in your paper.) confirm your test results using the 1-proportion function in minitab. report your conclusions, stated in terms of the data and the sampling scenario.

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

collect results in alphabetical order:

answer:   {x = -1/2 ,   y = -1
