Breaking Strength of Thread Matlab Help

Breaking Strength of Thread

To ensure proper quality control, a thread manufacturer selects samples and tests them for breaking strength. Suppose that 20 thread samples are pulled until they break, and the breaking force is measured in newtons rounded off to integer values. The breaking force ‘values recorded were 92, 94, 93, 96, 93,:94, 95, 96, 91, 93, 95,~, 95, 92, 93, 94, 91, 94. 92, and 93. Plot the histogram of the data.

Solution

Store the data in the vector y, which is shown in-the following script file. Because there are six outcomes (91, 92, 93, 94, 95, 96 N), we choose six bins. However, if you use hist (y , 6).the bins will not be centered at 91. 92, 93, 94, 95, and 96. So use the form hist (y,x ),where x = [ 91 :96].The following script file generates the histogram shown in Figure 7.1-2.
