Maribel is putting the finishing touches on her slide presentation. she wants
to make the slides more engaging for her audience, so she decides to insert
audio onto each slide. when she clicks to each new slide, a different song will
begin to play. why is this an example of poor design?

a. this use of audio is perfectly acceptable, and is actually an
example of good design.
b. use of audio in this manner will likely be distracting to her
audience, especially if the songs have no relation to the content on
the slides.

c. using multiple songs will likely be distracting to her audience. she
should instead just include one song that will play on repeat
throughout her entire presentation.

d. audio is less engaging for an audience, compared to video. she
should instead insert a video to play on each slide.

Ajustification for job training programs is that they improve worker productivity. suppose that you are asked to evaluate whether more job training makes workers more productive. however, rather than having data on individual workers, you have access to data on manufacturing firms in ohio. in particu- lar, for each firm, you have information on hours of job training per worker (training) and number of nondefective items produced per worker hour (output). (i) carefully state the ceteris paribus thought experiment underlying this policy question. (ii) does it seem likely that a firm’s decision to train its workers will be independent of worker characteristics? what are some of those measurable and unmeasurable worker characteristics? (iii) name a factor other than worker characteristics that can affect worker productivity. (iv) if you find a positive correlation between output and training, would you have convincingly established that job training makes workers more productive? explain.
