35 x -13 x 8 = -3640 - (-6) = -3640 + 6 = -3634
Divide both numbers down as low as they can go so 14:27 would be the answer

Answer:
-1.00
Step-by-step explanation:
Given that a publisher reports that 45% of their readers own a laptop. A marketing executive wants to test the claim that the percentage is actually different from the reported percentage.
Sample size n =190
Sample proportion p = 0.41
![H_0: p = 0.45\\H_a: p \neq 0.45](https://tex.z-dn.net/?f=H_0%3A%20p%20%3D%200.45%5C%5CH_a%3A%20p%20%5Cneq%200.45)
(Two tailed test )
Assuming H0 to be true
std error = ![\sqrt{pq/n} =\sqrt{0.45*0.55/155} \\=0.0400](https://tex.z-dn.net/?f=%5Csqrt%7Bpq%2Fn%7D%20%3D%5Csqrt%7B0.45%2A0.55%2F155%7D%20%5C%5C%3D0.0400)
p difference = -0.04
Test statistic = p differencce/std error
= -1
Hence test statistic is -1.00
