Three students want to estimate the mean backpack weight of their schoolmates. To do this, they each randomly chose 8 schoolmates and weighed their backpacks. Then as per the given sample data,
(a) The sample means of the backpacks are: 6.375,6.375,6.625
(b) Range of sample means: 0.25
(c)The true statement is: The closer the range of the sample means is to 0, the less confident they can be in their estimate.
For the first sample, mean= 6.375
For the second sample, mean= 6.375
For the third sample, mean= 6.625
Range of sample means=Maximum Mean- Minimum Mean
= 6.625 - 6.375
= 0.25
The students will estimate the average backpack weight of their classmates using sample means, the true statement is:
The closer the range of the sample means is to 0, the more confident they can be in their estimate.

The answer is: " 100 cultures " .
_______________________________________________
Take the number of the day we are at (from the beginning; in this case, "9" (for "Day 9").
_________________________________________________
Then add "1" to that number (in this case, " 9 + 1 = 10" .
_________________________________________________
Then, take that value (in this case, "10"); and "square" that value ; (in this case; " 10² = 10 * 10 = 100 . This is the answer.
