Given:
n = 48, the sample size
m = $25,000, th sample mean
σ = $3000, the maximum variance
The standard deviation is
s = √σ = √(3000) = 54.772
As a rule of thumb, the range is 4 times the standard deviation. Therefore the range is
R = 4*54.772 = 219.09
Half the range is
R/2 = 219.09/2 = 109.45
The required range is
(25000-109.45, 25000+109.45) = (24890.46, 25109.54)
Answer: ($24,890.46, $25,109.54)

Answer:
16443
Step-by-step explanation:
a = 7676 - b
b = -8767
then:
a = 7676 - (-8767)
a = 7676 + 8767
a = 16443
Check:
16443 -8767 = 7676
