Based on the percentage of readers who own a particular make of the car and the random sample, we can infer that there is sufficient evidence at a 0.02 level to support the executive claim.
<h3>What is the evidence to support the executive's claim?</h3>
The hypothesis is:
Null hypothesis : P = 0.55
Alternate hypothesis : P ≠ 0.55
We then need to find the test statistic:
= (Probability found by marketing executive - Probability from publisher) / √( (Probability from publisher x (1 - Probability from publisher))/ number of people sampled
= (0.46 - 0.55) / √(( 0.55 x ( 1 - 0.55)) / 200
= -2.56
Using this z value as the test statistic, perform a two-tailed test to show:
= P( Z < -2.56) + P(Z > 2.56)
= 0.0052 + 0.0052
= 0.0104
The p-value is 0.0104 which is less than the significance level of 0.02. This means that we reject the null hypothesis.
The Marketing executive was correct.

Answer:
And we can find this probability using the normal standard distribution table or excel and we got:
Explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the expected return, and for this case we know the distribution for X is given by:
Where 
and 
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability using the normal standard distribution table or excel and we got:
Informational Appeals help consumers make purchase decisions by offering factual information that encourages consumers to evaluate the brand favorably on the basis of the key benefits it provides.
<h3>What is Informational Appeals ?</h3>
It allows you to showcase the product's qualities and the benefits that a buyer will gain when using the goods. It is an effective method of persuading them that your product is something they truly require and can use. Con: Informative advertisements can be boring.
Aristotle proposed three types of argumentation arguments: logical, ethical, and emotional appeals.
Ebooks, "How-to" videos, blogs, and brochures are all examples of informational marketing because they provide a detailed description of a service or product and what makes it unique in the business.

Answer:
A larger industrial and service sector, and a larger number of people working outside of agriculture, can indicate a higher level of industrialization in the economy and vice versa. This means that the size of industrial service and the sector of agriculture employment rate indicates the level of industrialization because if the agriculture employment is higher than the industrial service it means that the country is not fully developed yet and therefore the level of industrialization is lower. But if the industrial service is higher than the agriculture employment that suggests or indicates that the country is developing or developed. For example in the United States the size of the industrial/service sector is much larger than it's agricultural employment and therefore this should suggest that country is much more industrialized or developed and the United States is. In comparison you take a developing country such as Chad and you can see that the agricultural employment is higher than the size of the industrial/service sector and in relation to this you can see that Chad must have a lower level of industrialization and in fact it does.
