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.

Answer:
The total number of cartons did he sale is 20 .
Step-by-step explanation:
Given as :
The total number package in each carton = 28
The total amount received after sale = $ 280
The cost of 10 noodles = $ 5
Let the total number of cartoon sale = x
According to question
∵ The number of noodles costing $5 is 10
so,The number of noodles costing $1 is 
= 2
∴ The number of noodles costing $280 = 2 × 280 = 560
Now, since there are 28 packages in 1 carton
So . the number of carton did he sale = 
Or, The number of carton did he sale = 
= 20
Hence The total number of cartons did he sale is 20 . Answer
