Subject:ArtsPrice: Bought3
1) Consider the argument below:
"In a factory that produces 10,000 widgets per day, 100 widgets are chosen each day for inspection. Over a year, 1.5% of the inspected widgets are found to be defective. Therefore, 1.5% of all the widgets produced by the factory are defective."

Group of answer choices
the students sampled live on campus.

3.Suppose that a survey is taken at a Rite Aid pharmacy in Michigan in which it is found that 70% of those surveyed have taken pain relievers during the past week. Kevin Smith shopped at Rite Aid during the past week. The conclusion that Kevin Smith took pain relievers during the past week

is weak because the sample size is small.
would be weak if it is known that Kevin Smith is very healthy and rarely takes pain relievers
is weak because the conclusion is drawn from knowledge of only one individual.
is a strong sampling argument.
4.Suppose that a survey is taken at a Rite Aid pharmacy in Michigan in which it is found that 70% of those surveyed have taken pain relievers during the past week. The conclusion that 70% of Michigan residents have taken a pain reliever during the past week is
Group of answer choices
strong, because of the high percentage found to have taken pain relievers in the survey during the past week
strong, because Rite Aid sells pain relievers.
weak, because the sample is likely not representative of those taking pain relievers.
weak, because the sample is too small.
5.Elise hears from a trusted neighbor that 10 burglaries occurred in her neighborhood during the past month. Her neighbor further laments that crime in their city is on the rise. Which of the following is not correct:
Group of answer choices
The sample here is weak because the sample size is too small.
The alleged burglaries occurred in a small area and so can't be taken to be representative of similar crimes elsewhere in the city.
The conclusion that crime is on the rise is probably true because it was said by a trusted neighbor.
No evidence of a rise in crime has been given.
