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.

Final Amount 10,400
soldi70 [24.7K]

Answer:

$9629.63

Step-by-step explanation:

I assume this is simple interest.

The formula for simple interest is

F = P(rt + 1)

where F = future value,

P = present value

r = annual interest rate

t = number of years

10,400 = P(0.02 × 4 + 1)

10,400 = 1.08P

10,400/1.08 = P

9,629.63 = P
