Researchers have been studying acorns produced by trees in a certain region. The acorns are used as a food source by various animals. The researchers have recorded the mass of a random sample of acorns (displayed below). Acorn mass (grams): 3.75, 4.51, 3.64, 3.76, 3.66, 3.46, 3.64, 4.16, 3.65, 3.76, 3.79 Checksum: 41.78 Resample the sample (bootstrap) (link to program &) with 1000 iterations to create a 90% confidence interval for the mean mass of all acorns: Result: The researchers can be 90% confident that the mean mass of all acorns in this region is between '1 l and | ' grams
