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

Currently a product has a gear ratio of 17:5, driver:driven. If the company wants to change the product to have the same gear ra

Sedbober [7]

Answer:

10 teeth must go on the driven gear

Step-by-step explanation:

Let the number of teeth be x

In order for the new product to maintain the same ratio as the old the ratio must remain the same. This means that

17:5 = 34:x

$\frac{17}{5} = \frac{34}{x}\\Now\ let\ us\ cross-multiply\\17 \times x = 5 \times 34\\17x = 170\\dividing\ both\ sides\ by\ 17 \\x = \frac{170}{17} \\x = 10$

∴ 10 teeth must go on the driven gear

hence ratio = 34:10
