A battery manufacturer claims that its midgrade battery has a mean life of 60 months with a standard deviation of 66 months. Suppose the distribution of battery lives of this particular brand is approximately normal. On the same assumption, 1) Find the standard error of sampling distribution of sample mean ( X )
