Answer:
s= 30000+1500x
Step-by-step explanation:
Given data
Le the number of years be x
His salary for the first year is $30,000
5% of $30,000
=5/100*30000
= 0.05*30000
= $1500
Hence for x years the salary can be described as
s= 30000+1500x
The distribution is not a standard normal distribution.
We know that the variable (X) usually obeys and follows a standard normal distribution provided that the summation of (X) is zero and the variance of the random variable V(X) = 1.
Mathematically:
E(X) = 0 and V(X) = 1
Given that;
- the mean which follows a normal distribution (X) = 4.5338 g, and
- the standard deviation SD(X) = 0.1039 g
As such, the distribution is not a standard normal distribution.
Therefore, we can conclude that the distribution is not a standard normal distribution.
