The Spokesman-Review wants to know the public opinion on the construction of a new library downtown. It is decided that 48 people will be surveyed using a simple random sample. Which of the following will produce a simple random sample? (1 point) Number the residents using the latest census data, then use a random number generator to pick 48 people. Record the opinion of the first 48 people who visit the newspaper's website. Survey every fourth person who enters the current library until 48 have responded. Randomly select 48 people from the phone book. Randomly select 12 people each from the downtown, south hill, northwest, and hillyard parts of the city.
what are your thoughts on it
Maybe A or D?
hint: one of them is cluster sampling
I think its A?
I don't know, I'm really confused on this question..
which one is the cluster sampling
which one is where they divide the people up by geographic location
yes, so that isn't a SRS
Is the SRS A?
yes it's the best way because `Randomly select 48 people from the phone book.` implies that only people in the phone book will be picked those with cell phones or without phones won't be picked
