Answer:
E.  Faced with a negative population growth rate, the country relaxed immigration control norms 25 years ago.
Explanation:
Given that<u> immigrants increase the population</u> and that they may come from a less healthy environment, having a less healthy background is very common for them. Even if the domestic population had a high average height, t<u>he mean value will surely decrease</u> to the lower height of the immigrants.
Therefore, a correlation between economic growth and average health measured by height can be undermined, given E) is true.

Answer: introduce more differentiation
Explanation: Product differentiation is a method of using various tactics to make a product stand out from the rest of the similar products sold by a competitor, in an effort to make it more appealing to its customer base. This means differentiating the product so much, that it will make it more attractive for customers to buy. This can be anything from making the product's packaging more aesthetically appealing, including some form of a bonus/gift for purchasing the product (like getting a free toy in each cereal box) etc. In the end by applying product differentiation the one company will increase the customer benefits of purchasing this product from them, hereby gaining a competitive advantage over the other company. 
 
        
             
        
        
        
Answer:
The president of Riggs has missed something.
She should make the Sail instead of buying because its cheaper to manufacture than purchasing it outside.
Explanation:
<u>Cost of Manufacturing the Sails:</u>
Direct materials        $93
Direct Labor              $83
Total                         $173
The president of Riggs has included the $90 overhead  based on $78,000 of annual fixed overhead that is allocated using normal capacity in the cost of manufacturing the sail which is incorrect.
Riggs Company is operating at 80 % of full capacity, hence utelizing the 20% excess capacity would not expand its fixed costs.
Thus said the current fixed cost are irrelevent for this decison and would be incurred whether or not Riggs Company utilizes the excess capacity
<u>Conclusion:</u>
The cost of making the sail is $173 which is lower than the cost of buying them at $ 258.
I would advise The president of Riggs to make the sail by utilizing the excess capacity since its cheaper than purchasing it outside.
