Background<\/span><\/h3>\n

Six units are tested to failure. The objective is to use the complete data from the analysis to obtain a probability plot with 90% 2-sided confidence bounds and a pdf<\/i> plot.<\/p>\n

Experiment and Data<\/span><\/h3>\n

The following failure times are observed for 6 units: 11,260; 12,080; 12,125; 12,825; 13,550 and 14,670 hours.<\/p>\n<\/div><\/div>

Analysis<\/span><\/h3>\n

Step 1:<\/b> The parameters for the data are calculated using the normal distribution and rank regression on X as the parameter estimation method, as shown next.<\/p>\n<\/div>
