Identify the sampling technique used. in a recent television survey, participants were asked to answer "yes" or "no" to the question "are you in favor of the death penalty? " six thousand five hundred responded "yes" while 51 00 responded "no". there was a fifty- cent charge for the call.

Convenience sampling. See explanation below.

Step-by-step explanation:

For this case they not use random sampling since all the individuals for the population are not included on the sampling frame, some individuals have probability of inclusion 0, because they are just using a charge for the call and some people would not answer the call.

Is not stratified sampling since we don't have strata clearly defined on this case, and other important thing is that in order to apply this method we need homogeneous strata groups and that's not satisfied on this case.

Is not systematic sampling since they not use a random number or a random starting point, and is not mentioned, they just use a call that is charge with 50 cents.

Is not cluster sampling since we don't have clusters clearly defined, and again in order to apply this method we need homogeneous characteristics on the clusters and an equal chance of being a part of the sample, and that's not satisfid again with the call charge used.

So then the only method that can be possible for this case is convenience sampling because they use a non probability sampling with some members of the potential population with probability of inclusion 0.

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
