Answer:
-27
Step-by-step explanation:
Solve the system of equations by elimination
Multiply the second equation by 2
-5x + 2y = -51
-2x -2y = -12
Combine
-7x = -63
x = 9
Then, find y by plugging in 9 for x
-(9) - y = -6
-y = 3
y = -3
Then, multiply x by y
(9)(-3) = -27
Answer:
when the advertiser failed to reject the null hypothesis it means that the belief of the newsletter publisher that ess than 26% of their readers own a Rolls Royce is not supported by statistical evidence at 10% significance level.

H0: p = 0.26
Ha: p <0.26
