First, add three to both sides on the equation. Then, your equation becomes 55= -5x. Finally, divide both sides by -5 to get -11 = x. So, x equals -11. Hope this helps!

A major airline company is concerned that its proportion of late arrivals has substantially increased in the past month. Histori

lutik1710 [3]

Answer:

The correct statement is

The null hypothesis is $H_o : p = 0.18$

The alternative hypothesis is $H_a : p > 0.18$

Step-by-step explanation:

From the question we are told that

The population proportion is p = 0.18

The sample size is n = 1240 airplane

The number of airplane is k = 310

Generally the sample proportion is

$\^ p = \frac{k}{n}$

=> $\^ p = \frac{310}{1240}$

=> $\^ p =0.25$

The null hypothesis is $H_o : p = 0.18$

The alternative hypothesis is $H_a : p > 0.18$
