Answer:
Mean and standard deviation of the sample mean are 225.8 and 3.56 respectively.
Step-by-step explanation:
The mean (μₓ) and standard deviation of the sample mean (σₓ) are related to the mean (μ) and standard deviation of the population (σ) through the following relationship
μₓ = μ = 225.8
σₓ = σ/√n = 17.8/√25 = 17.8/5 = 3.56
Using I = PRT
$2500 - $2000 = $2000 × 0.04 × t
$500 = 80t
t = $500 ÷ 80
t = 6.25 years
so the answer is 6
