2% of the populatiuomn of manufactured pars are defective as the routine outcome of process. Control tech periodically samples 100 parts to find if process is in control.
i) Find population Pn=100, for sampling distribution of proportions for sample of defective parts of n=100?
ii) Find standard deviation of sampling distribution Opbar for n=100?
The population distribution has the mean of 99 with the standard deviation of 4. Let sampling distribution for sample size of 64
iii) Find mean of sample distribution?
iv) Find standard deviation of the sampling distribution?
