comment How to predict/find a value based on historical data using statistics?
Anything's possible - you need to include information about what the numbers mean for anyone to suggest a appropriate method. Are they a time series? Can you safely assume the values are scattered around a constant average with a constant spread? Is a trend likely?

comment Changing a target value that minimize the product being outside the specifications in quality control
(b) The normal distribution is symmetric & unimodal. So imagine nudging it along relative to the specs - at what point does a nudge push more of the density over the upper spec than it pulls over the lower spec? (b) Give more of your working.

comment Calculation of RMSE and $R^2$ to compare five numerical methods for determining Weibull parameters
If the "best" estimation method is the one that gives the lowest root mean square error on the sample, then why not use parameter estimates that minimize RMSE? Might be useful to read up on what properties define a good estimator in general.
