Step-by-step explanation:
Amount invested = Principal = 180,000
Interest rate = 5.75%
Time = 1 year
The interest that is earned at the end of the first year will be:
= PRT
= 180,000 × 5.75% × 1
= 180,000 × 0.0575 × 1
= 10350
The random variable X is normally distributed with mean μ=30 and standard deviation σ =10.
Use the transformation
for calculating the probability. This value is called Z-score.
The Z score is
.
Refer to the standard normal distribution table.
