Question 8 • NC-Math 4
The owner of an apple orchard knows that the average weight of Granny Smith apples is 380 grams. A random sample of 40 apples was selected, and the mean weight was 390 grams. Let μ = the true mean weight of the Granny Smith apples in the orchard. Under the assumption that the true mean weight of Granny Smith apples is 380 grams, 100 simulated means for samples of size 40 are shown in the dotplot.What does the dot above 371 represent?
Answer
A
The majority of the samples of Granny Smith apples had mean weights greater than 371 grams.B
In one simulated random sample of 40 Granny Smith apples, the mean weight of the sample was 371 grams.C
In one simulated random sample of 40 Granny Smith apples, the mean weight of the population was 371 grams.D
There is a 1 out of 100 chance that a random sample of 40 Granny Smith apples will have a mean weight of 371 grams.
