Nine diodes were sampled to measure the manufactured diode’s forward voltage as shown in the table above. Use these data to calculate three interval types (shown below. For all computations, assume an approximately normal distribution. The mean sample and standard deviation for the given data are ?̅ = 0.7 ? and ? = 0.1 ?. 

a. Find a 99% confidence interval on the mean forward voltage drop.


b. Compute a 99% prediction interval on a measured forward voltage of a diode after manufacturing.


c. Find the 99% tolerance limits that will contain 95% of the diodes manufactured.
