A publisher reports that 45% of their readers own a laptop. A marketing executive wants to test the claim that the percentage is actually different from the reported percentage. A random sample of 370 found that 40% of the readers owned a laptop. determine the p-value of the test statistic

Step-by-step explanation:

Information given

n=370 represent the sample selected

estimated proportion of  readers owned a laptop

is the value that we want to test

z would represent the statistic

represent the p value

Creating the hypothesis

We need to conduct a hypothesis in order to test if the true proportion of readers owned a laptop is different from 0.45, the system of hypothesis are:  

Null hypothesis:  

Alternative hypothesis:  

The statistic is:

(1)  

Replacing we got:

Calculating the p value  

We have a bilateral test so then the p value would be:

4x and 6y

im not sure though

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
