Find the standard deviation of the following set of numbers: 10,15,19,35,27,44. Round your answer to the nearest tenth.
To find the standard deviation of a set of numbers, first find the mean (average) of the set of numbers:
10+15+19+35+27+446=25
Second, for each number in the set, subtract the mean and square the result:
(10−25)2+(15−25)2+(19−25)2+(35−25)2+(27−25)2+(44−25)2=826
Then add all of the squares together and find the mean (average) of the squares, like this:
8266=137.67
Finally, take the square root of the second mean:
137.7‾‾‾‾‾√=11.7.

Type this matrix into a MATLAB Script File to carry out the following instructions:𝐀 = [ −5 9 10 6 13 8 15 5 4]
a. Use MATLAB to create a vector 𝐵⃗ using the elements from the first row of matrix 𝐀.
b. Use MATLAB to create a vector 𝐶 using the elements from the third column of matrix 𝐀.
A = [-5 9 10; 6 13 8; 15 5 4]
B = A(1,:)
C = A(:,3)
