# Question: The failure time in hours of 10 memory devices follows

The failure time in hours of 10 memory devices follows: 1210, 1275, 1400, 1695, 1900, 2105, 2230, 2250, 2500, and 2625. Plot the data on normal probability paper and, if appropriate, estimate the process capability. Is it safe to estimate the proportion of circuits that fail below 1200 h?
