Question

24 Run rand (1,N) 4 times where N takes on 4 ditterent values: 100, Poo, 1000, 10000. Each time you run rand (1,N), plot a histogram using 20 bins displayed on a 2x2 aubplot roma t as shown in Fig. 1 posted on Canvas. Notice how the histogram looks more and more like the underlying uniform distribution on [0,1] as 4 the number of samples increases. Put the number of samples in the ticie i of each graph. For subplot (2,2,1), include your name in the title. Again, see 25 26 27 28 29 30 Fig. 1 as posted. Title font size 16. took back at 2100 slides for help with the title. 31

Explanation / Answer

% select first subplot

subplot( 2 , 2 , 1 );

title('100 Samples');

% create 100 random numbers

arr1 = randn(1 , 100);

nbins = 20;

% plot the histogram

histogram(arr1 , nbins);

% select second subplot

subplot( 2 , 2 , 2 );

title('500 Samples');

% create 500 random numbers

arr2 = randn(1 , 500);

nbins = 20;

% plot the histogram

histogram(arr2 , nbins);

% select third subplot

subplot( 2 , 2 , 3 );

title('1000 Samples');

% create 100 random numbers

arr3 = randn(1 , 1000);

nbins = 20;

% plot the histogram

histogram(arr3,nbins);

% select fourth subplot

subplot( 2 , 2 , 4 );

title('10000 Samples');

% create 10000 random numbers

arr4 = randn(1 , 10000);

nbins = 20;

% plot the histogram

histogram(arr4 , nbins);
