Researchers wondered if there was a difference between males and females in regard to some common annoyances. They asked a rando
Zinaida [17]

Answer:

Step-by-step explanation:

Males proportion p_1 = \frac{163}{532} =0.3064

Females proportion p_2 = \frac{203}{589} =0.3447

H_0: p_1 = p_2\\H_a: p_1

(one tailed test for comparison of proportions)

Test statistic = \frac{p_1-p_2}{p(1-p)\sqrt{\frac{1}{n_1}+\frac{1}{n_2}  } }

=-1.3641

Here p= combined proportion = \frac{163+203}{532+589} \\=0.3291

p value = 0.0869

Since p >0.05, accept null hypothesis.

The evidence does not suggest a higher proportion of females are annoyed by this​ behavior

We get 2/7 x 1/4 = <em>1/14</em>
