Answer: 4150

Step-by-step explanation:

You take the 50, becuse the amount earned increases once you surpass 40 you do 40 x 10 and that = 4000 then you take the remaining 10 and times that by 15 (becuse after 40 it is 1.5 of what you where earning before you hit 40 hours and half of ten is 5 so you do 10 plus 5 and times that by 10) then add both numbers together and you have 4150! Hope that helped!

Two different simple random samples are drawn from two different populations. The first sample consists of 20 people with 9 havi
QveST [7]

Answer: (-0.48,\ -0.04)

Step-by-step explanation:

The confidence interval for the difference of two population proportion is given by :-

(p_1-p_2)\pm z_{\alpha/2}\sqrt{\dfrac{p_1(1-p_1)}{n_1}+\dfrac{p_2(1-p_2)}{n_2}}

Given : The first sample consists of 20 people with 9 having a common attribute.

Here, n_1=20 , p_1=\dfrac{9}{20}=0.45

n_2=2100 , p_1=\dfrac{1492 }{2100}\approx0.71

Significance level : \alpha=1-0.95=0.05

Critical value : z_{\alpha/2}=1.96

A 95% confidence interval for the difference of two population proportion will be :-

(0.45-0.71)\pm z_{\alpha/2}\sqrt{\dfrac{0.45(1-0.45)}{20}+\dfrac{0.71(1-0.71)}{2100}}\\\\\approx -0.26\pm0.22\\\\=(-0.26-0.22,-0.26+0.22)\\\\=(-0.48,\ -0.04)
