Resistances. An automat produces resistors whose experience has shown that they are realizations of a normally distributed random variable with µ = 1000 Ω and σ = 20 Ω. Resistances outside the tolerance limits of 960 Ω and 1050 Ω count as rejects. 1. How many of 950 resistors are on the middle committee? 2. The proportion of resistors with a value greater than 1050 Ω should be reduced to an average of 0.1%. How large must µ be if...

Variance: A company produces several thousand nominally identical resistors each day. An operator tested a sample of 100 resistors and obtained an average resistance of Ro=100 ohms with a standard deviation of S= 10 ohms. (a) If the operator discards 5% of the resistors as too high and another 5% as too low find the high and low acceptable limits? (b) What is the level of significance, level of confidence and the confidence interval for resistors having a value greater...
