Answer:

The given graph represents perfect negative association between variable X and variable Y.

Step-by-step explanation:

The given graph represents the relation between the variable X and variable Y.

From the given graph it is clear that all the points lie on a straight line. It means the graph represents the perfect association.

The value of Y decreases as X increases. It means variable X and variable Y negatively associated.

Therefore the given graph represents perfect negative association between variable X and variable Y.

Prove that 3: 8 is equivalent to 12: 32

Kazeer [188]

3:8 can also be written as 3/8

12:32 can also be written as 12/32

$\frac{12}{32} = \frac{3\times 4}{8\times 4} = \frac{3}{8}$

So thus 3:8 is equivalent to 12:32

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
