Could Someone Provide the Sample Output for these Two Programs? I don't own MATLAB or if you know another way for me to get sample output.. thank you.

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);

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);

Here you go.

1. MATLAB Program

   answer_a =
       1
answer_b =
      1.4854
answer_c =
      0.1598

2. MATLAB Program

   answer_a =
      0.4900
answer_b =
      5.0114
answer_c =
      0.2052

Hang on a second before using them! Since they are generated randomly, let me do one more trial and update it!

Google octave or scilab. Both these are open source and almost like MATLAB.
