1. MATLAB Program
nsamples=100;  % number of samples
n = 225;  % sample size 225
a = 1;
b = 2;
data = -3+9*rand(nsamples, n);  % random 100x225 data sample from a uniform (0,1) distribution
cMean = mean(data, 2);  % mean of each sample
answer_a = sum(cMean > a & cMean < b)/nsamples;  % how many data means are between a and b
answer_b = mean(cMean);
answer_c = std(cMean, 1);
hist(cMean);

xlabel('Z');  %labeling x-axis
ylabel('Frequency');  %labeling y-axis
2. MATLAB Program
nsamples=400;  % number of samples
n = 625;  % sample size 625
a = 3;
b = 5;
lambda = 0.2;
data = -log(rand(nsamples, n)) / lambda;  % random 400x625 data sample from a uniform (3,5) distribution
cMean = mean(data, 2);  % mean of each sample
answer_a = sum(cMean > a & cMean < b)/nsamples;  % how many data means are between a and b
answer_b = mean(cMean);
answer_c = std(cMean, 1);
hist(cMean);
