A researcher wants to know how dog owners in the United States feel about establishing a law requiring individuals who own pit b

ulls to obtain insurance for their dog. The researcher mails a survey to a random sample of 5,000 owners out of all registered dog owners in the
US. A total of 2,389 out of the 5,000 respond and 22% say they favor the law. Which of the following is true based on this information?

Select one:

a. There is sufficient evidence that the percentage of all dog
owners who say they favor insurance for pit bulls is close to
22% because random sampling was used.

b. There is sufficient evidence that the percentage of all dog
owners who say they favor pit bull owners obtaining insurance for their dog is close to 22% because less than half of those who were mailed the survey responded.

c. The results of this survey are invalid because the survey was
mailed and not a face-to-face interview.

d. There is evidence of nonresponse bias in the survey results.

e. There is strong evidence of convenience response bias in the survey results.

There is evidence of non-response bias in the survey results because only a fraction of the people that were mailed responded.

<h3>What is a survey?</h3>

A survey is a type of research which seeks to obtain information from a specific group of people called respondents. The research is normally in form of a questionnaire the reflects the honest opinion of the respondent.

From the result of the survey, it is possible to conclude that there is evidence of non-response bias in the survey results because only a fraction of the people that were mailed responded.

Answer:

<h2>C. 9x³ − 11x² − 7x </h2>

Step-by-step explanation:

f(x)=36x^5-44x^4-28x^3\\\\g(x)=4x^2\\\\\dfrac{f(x)}{g(x)}=\dfrac{36x^5-44x^4-28x^3}{4x^2}\\\\\dfrac{f(x)}{g(x)}=\dfrac{(4x^2)(9x^3)-(4x^2)(11x^2)-(4x^2)(7x)}{4x^2}\\\\\dfrac{f(x)}{g(x)}=\dfrac{(4x^2)(9x^3-11x^2-7x)}{4x^2}\qquad\text{cancel}\ 4x^2\\\\\dfrac{f(x)}{g(x)}=9x^3-11x^2-7x

In a study of the accuracy of fast food​ drive-through orders, one restaurant had orders that were not accurate among orders obs
Evgesh-ka [11]

Answer:Null hypothesis:  

Alternative hypothesis:  

 

 

The p value obtained was a very high value and using the significance level given  we have  so we can conclude that we have enough evidence to FAIL to reject the null hypothesis, and we can said that at 5% of significance the proportion of orders that were not accurate is not significant different from 0.1 or 10% .  

and the accuracy of the test yes is acceptable since the p value obtained is large enough to fail to reject the null hypothesis

Step-by-step explanation:

Data given and notation n  

n=367 represent the random sample taken

X=32 represent the orders that were not accurate

estimated proportion of orders that were not accurate

is the value that we want to test

represent the significance level

Confidence=95% or 0.95

z would represent the statistic (variable of interest)

 

Alternative hypothesis:  

When we conduct a proportion test we need to use the z statisitc, and the is given by:  

(1)  

The One-Sample Proportion Test is used to assess whether a population proportion  is significantly different from a hypothesized value .

Calculate the statistic  

Since we have all the info requires we can replace in formula (1) like this:  

 

Statistical decision  

It's important to refresh the p value method or p value approach . "This methos is about determining "likely" or "unlikely" by determining the probability assuming the null hypothesis were true of observing a more extreme test statistic in the direction of the alternative hypothesis than the one observed". Or in other words is just a method to have an statistical decision to fail to reject or reject the null hypothesis.  

The significance level provided . The next step would be calculate the p value for this test.  

Since is a bilateral test the p value would be:  

 

So the p value obtained was a very high value and using the significance level given  we have  so we can conclude that we have enough evidence to FAIL to reject the null hypothesis, and we can said that at 5% of significance the proportion of orders that were not accurate is not significant different from 0.1 or 10% .
