Hello :D

A mutually exclusive event is something that can't happen at the same time. An example of this is tossing a coin. You can't get heads and tails at the same time. This is a mutually exclusive event.

Hope this helps :)

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 :-

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

Answer:

Dependent variable:

Academic success of Japanese and American students

Step-by-step explanation:

We are given the following in the question:

Experiment:

Assessing the impact of videos games upon the academic success of Japanese and American students

Dependent and independent variable:

The independent variable is the free variable.
It's value does not depend on any other variable.
The dependent variable is the variable whose value depends on another variable.
A change in the independent variable leads to a change in the dependent variable.

Thus, for the given experiment,

Dependent variable:

Academic success of Japanese and American students

Independent variable:

Videos games
