Question

determine the sampling method used in the following scenario: farmer lennie wants to advertise the weight of cows on her farm. instead of weighing all the cows, she decides to weigh a sample of 465 cows. she gathers a list of cows from the farms ledger, which hasnt been updated since the last harvest. she randomly selects one cow from a list and then selects every 9th cow after that until 465 are selected. simple random sampling (srs) stratified sampling systematic sampling cluster sampling convenience sampling voluntary response sampling purposive sampling snowball sampling quota sampling yes, we should expect this sample to be biased no, we should expect this sample to be unbiased

Explanation:

Systematic sampling involves selecting every k - th element from a list. Here, Farmer Lennie randomly selects one cow and then selects every 9th cow until she has 465 cows. Also, the list hasn't been updated since the last harvest, which may lead to bias as the current population of cows might be different from what's on the list.

Answer:

Systematic sampling
Yes, we should expect this sample to be biased
