A company develops a drug that they claim would make their consumers feel 'happier and more excited with life'. They plan to conduct an experiment to test this claim. In choosing their subjects, they plan to post invitations on a messageboard of a nearby university asking whether students would be interested in 'being the first to try out our new amazing drug!'. Those that volunteer are brought into company headquarters and given the drug. After a few hours of various activities, including lunch, they answer questions on a standard psychological test of happiness and engagement. Select all of the following problems that are likely to arise with such an experiment: a. non-response.
b. undercoverage.
c. placebo effect.
d. poorly worded survey questions.
e. bias due to a voluntary response sample.

The following problems that are likely to arise with such an experiment is:

B. Undercoverage

C. Placebo effect.

E. Bias due to a voluntary response sample.

B. Under coverage -

C. Placebo effect-

E. Bias due to a voluntary response sample.

Thus, the correct option is B, C and E.

b. undercoverage

c. placebo effect.

e. bias due to a voluntary response sample.

Step-by-step explanation:

Undercoverage because the invitation does not cover for a good amount of university students. It is only given to university students that are nearly

Placebo effect occurs due to the fact that the drug is given to all the sample participants so it will be very difficult differentiating any effect that is above the placebo response. Therefore, the placebo effect is a main problem.

Voluntary Response Bias in survey sampling, this happens due to the fact that sample participants are volunteers that were self selected.

step-by-step explanation:

points are handed out whenever you post answers.

brainliest answers are handed out by the person asking the question, so whether your answer is picked depends entirely on whether the asker bothers to pick

if you're asking about your rank, it depends on having a certain number of points and a certain number of brainliest answers. for example, at the time of this writing, i have 44338 points out of 15000 needed for the next (nearly triple the requirement! ) but i only have 24 out of 50 required brainliest answers. this number decays, meaning after a certain amount of time (i think about a month), the total number of brainliest answers you've earned doesn't count toward this total. (i've been stuck at the same rank for a long

the lesson to learn here is that you shouldn't worry about points or rank. chances are, no matter how good an answer you may provide, your efforts will go mostly unnoticed unless you focus on the newest/most active questions that get posted.
