I am one of the numbers represented on a number line when you divide the segment between -15 and 25 into 4 equal parts. I am pos

Aliun [14]

Answer:

2, 3, 5, 7, 11, 17, 19, 23

Step-by-step explanation:

The segment between - 15 and 25 has 40 numbers given by

25 - -15

= 25 + 15

= 40

Divided into 4 segments, each would contain 10 numbers such that the

1st segment is from -15 to -5 (which is -15 + 10)

2nd segment is from -5 to 5 (which is -5 + 10)

3rd segment is from 5 to 15 (which is 5 + 10)

4th segment is from 15 to 25 (which is 15 + 10)

Given that the unknown number is prime and positive this may be

2 or 3 or 5 from the 2nd segment

7 or 11 from the third segment

17 or 19 or 23 from the 4th segment

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 :-

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