Multiple Choice
Noxious weeds are invasive plants that quickly spread and deplete the soil of nutrients that are required for all aspects of farming and ranching. With much at stake, the state of Montana has hired a team of researchers to explore the issue. They want to know the average number of noxious weeds per acre in North Central Montana. To do so, researchers divided the area of interest into 1,000,000 acres and randomly selected 24 of these acres. For each selected acre, they counted and removed the noxious weeds. The sample mean was 103.47 weeds, and the sample standard deviation was 46.034 weeds. Below is the simulated bootstrap distribution of 1,000 sample means they created from resampling the observed data.
-Can we use this study to generalize our results to the population of interest?
A) No, since we only observed 24 acres.
B) Yes, since we randomly selected the 24 acres from all 1,000,000 acres.
C) No, since we only generated 1,000 bootstrapped samples.
D) Yes, since our results were statistically significant.
