A sociologist collected data from a sample of people on their highest level of education and the number of times they visited any fast food restaurant during the previous week. The data are summarized in the boxplots. Based on the boxplots, which of the following statements must be true?a. The number of people surveyed at the more than four-year college level is greater than the number of people surveyed at the high school level.
b. The proportion of people surveyed from the first quartile to the third quartile at the four-year college level is less than the respective proportion at the community college level.
c. The interquartile range (IQR) for the number of visits at the more than four-year college level is less than the IQR for the number of visits at the community college level.
d. The maximum number of visits at the community college level is greater than the maximum number of visits at the high school level.
e. The median number of visits at the four-year college level is greater than the median number of visits at the high school level.

The correct answer is A. Buying cheaper alternatives when a product becomes expensive

Explanation:

In economics the substitution effect refers to the effect a rise in the price of a specific product has on the consumers choice, this implies when the price of some specific product rises and the income of consumers remains unchanged, the consumer will decide to buy similar but cheaper products or the alternative product, substituting more expensive products for cheaper alternatives. Similar results can be obtained if the price of a specific product falls and the product consumers buy remain the same, which will lead consumers to substitute the usual product they buy by the alternative cheaper product. Thus, the phrase that describes substitution is buying a cheaper alternative when a product becomes expensive, which means consumers choose similar but cheaper products if the usual product price rises.

Answer:

B. Display a sense of musical phrasing

Explanation:

This is a very interesting question that, depending on who reads it, the answer may change, especially because when it comes to babies there is not an absolute consensus about what is really going on in their brains. Besides, with the day to day advances in neuroscience there is always something new we understand (or realize we dont understand at all!) about the brain. In my case, I got to answer B just by aplying some logic:

A) "Prefer nonspeech over human speech". There are two main reasons why i think this cannot be the correct choice: first, when babies are around 7 months they start trying to imitate verbal communication of their parents, and, second, because it seems very unrealistic to say that a baby (4-7 months old) is actually prefering one way of speech over another.

C) "Prefer pieces of music with awkward breaks rather than those with pauses between phrases". This is an answer we can certainly put aside because of it subjective and demeaning way of expressing (i.e "awkward breaks").

D) "Listening to a foreign language rather than their native tongue".  Again, two reasons, first the "preference" assumption, and secondly, assuming a baby would understand the difference between two diferent tongues is laughable.

B) Display a sense of musical phrasing. I would think this is the correct choice, not only because the other possible questions are clearly faulty, but also because I have encountered with multiple articles in which the music importance in the language and cognitive development of the baby is shown.

Hope this helps!
