Question

I'm not too sure what the question is asking for when calculating for S, we need to use MatLab for writing the script. If anybody could be of some assistance, I need the script, and the sample output to match

8. Let n be the number of elements in a data set and let x denote an individual element, for i 1,2,. .. , n. The mean /u and standard deviation s are given by ηΣ α-(ΣΗ ) n(n - 1) n Li=1 Xi and n Write a script that first prompts the user for a minimum number fMin and a maximum number fMax. We consider the case when n = 5 (your program need not work for any other n value). The script should then generate random numbers T1, x2, ... , xn between fMin and fMax. As each number is generated, use a running sum fSum to calculate i and another running sum f Sum2 to calculate 7_1 x?. Use these results to calculate the mean fMean and standard deviation fStdDev and then print them. Sample output: Enter minimum number: -10 Enter maximum number: 10 -2.13, Sum of xi 2 so far is -2.13, Sum of xi so far is 8.03, Sum of xi so far is -2.11, Sum of xi so far is 4.53 Random number 1 is 69.05 Random number 2 is 5.90, Sum of xi"2 so far is 3.79, Sum of xi"2 so far is -0.59, Sum of xi 2 so far is 5.92, Sum of xi 2 so far is 73.50 Random number 3 is Random number 4 is -4.39, Sum of xi so far is 92.76 Random number 5 is 6.51, Sum of xi so far is 135.19 The mean is 1.18 The standard deviation is 5.66 Enter minimum number: 0 Enter maximum number: 20 Random number 1 is 18.19, Sum of xi so far is 18.19, Sum of xi^2 so far is 331.04 Random number 2 is 10.99, Sum of xi so far is 5.17, Sum of xi so far is 29.19, Sum of xi^2 so far is 34.36, Sum of xi*2 so far is 451.86 Random number 3 is 478.63 Random number 4 is 16.10, Sum of xi so far is 50.46, Sum of xi"2 so far is 737.82 Random number 5 is 14.30, Sum of xi so far is 64.76, Sum of xi"2 so far is 942.40 The mean is 12.95 The standard deviation is 5.09

fMin=input("Enter minimum number: ");

fMax=input("Enter maximum number: ");

fSum1=0;

fSum2=0;

for i=1:5

x=rand*(fMax-fMin)+fMin;

fSum1=fSum1+x;

fSum2=fSum2+x^2;

fprintf("Random number %d is %.2f, Sum of xi so far is %.2f, Sum of xi^2 so far is %.2f\n",i,x,fSum1,fSum2);

end

fMean=fSum1/5;

fStdDev=sqrt((5*fSum2-fSum1^2)/(5*4));

fprintf("The mean is %.2f\nThe standard deviation is %.2f\n",fMean,fStdDev);

Kindly revert for any queries

Thanks.
