Answer: Linda earns more interest
Step-by-step explanation:
Linda: 90000 x 1.06^3 -90000 = 17191.44
Bob: (90000 x 1.06 - 90000) x 3 = 16200
17191.44 > 16200
The standard deviation is 1.43 below the mean
<h3>How to determine the number of standard deviation?</h3>
The given parameters are:
Mean = 98.249
Standard deviation = 0.733
x = 97.2
To calculate the number of standard deviation below the mean, we use
![x = \bar x - n\sigma](https://tex.z-dn.net/?f=x%20%3D%20%5Cbar%20x%20-%20n%5Csigma)
So, we have:
![97.2 = 98.249 - n * 0.7333](https://tex.z-dn.net/?f=97.2%20%3D%2098.249%20-%20n%20%2A%200.7333)
Evaluate the like terms
![-1.049 =- n * 0.7333](https://tex.z-dn.net/?f=-1.049%20%20%3D-%20n%20%2A%200.7333)
Divide both sides by -0.733
n =1.43
Hence, the standard deviation is 1.43 below the mean
