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.

% times amount of each part = % times amount of mix
x = amount of 10%
100 = amount of 100%
x + 100 = amount of 40% mix
10x + 100(100) = 40(x + 100)
10x + 10,000 = 40x + 4,000
-10x - 4000.....-10x - 4000
------------------------------------- 6000 = 30x
so x = 6000 ÷ 30 = 200 mL
