I have mac osx and tried installing scilab and octave for the past 2 hours and hasn't worked… here are the programs, thanks..
1.
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_1a = sum(cMean > a & cMean < b)/nsamples % how many data means are between a and b
answer_1b = mean(cMean)answer_1c = std(cMean, 1)hist(cMean);title('Generating 100 Samples of Size 225 Simulated U(-3,6) Random Numbers Histogram Question 1 Part d)'); %title of histogram
xlabel('Z'); %labeling x-axis
ylabel('Frequency'); %labeling y-axis
2.
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_2a = sum(cMean > a & cMean < b)/nsamples % how many data means are between a and b answer_2b = mean(cMean) answer_2c = std(cMean, 1) hist(cMean); title('Generating 400 Samples of Size 625 Simulated Lambda = 0.2 Random Numbers Histogram Question 2 Part d)'); %title of histogram xlabel('Z'); %labeling x-axis ylabel('Frequency'); %labeling y-axis
