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:

news channels,news papers,and the internet

answer: answer is c!

ok i got to organize the

3/15 and 12/55

3*

aha

3*4 equals 12 but not
