Step-by-step explanation:
Here in this question, we want to calculate the mean absolute deviation of the data.
The first thing we will do here is to calculate the mean;
= (74 + 79 + 76 + 85 + 87 + 83 + 86 + 78)/8 = 81
Now, the next thing to do here is to calculate how far each of the values have deviated from the mean. This can be calculated by subtracting the mean from each individual value;
This is presented in the table on the attachment, please check attachment for this
Afterwards, we find the absolute value of all these subtractions then divide by 8 which is the number of values in the data.
Mean absolute deviation = Sum of all absolute deviations/number of values in dataset
He pays in interest of $111.0375. Interest is calculated in the two ways, by compounding or by simple interest.
<h3>How to calculate simple interest amount?</h3>
If the initial amount (also called as principal amount) is P, and the interest rate is R % annually, and it is left for T years for that simple interest, then the interest amount earned is given by:
The given data in the problem is;
The principal is,P=$2700
The rate of interest = 3.5%
The total time interval is,T
The total time interval is;
The simple interest is found as;
Hence, he pays in interest of $111.0375.
