Asimple random sample of 100 batteries is selected from a process that produces batteries with a mean lifetime of 32 hours and a standard deviation of 3 hours. thus the standard deviation of the sampling distribution is equal to 0.3.
if the sample size is changed to 400, what is the new standard deviation of the sampling distribution? a. it is oneāfourth as large as when n = 100.b. it is oneāhalf as large as when n = 100.c. it is twice as large as when n = 100.d. it is four times as large as when n = 100.e. the value of Ļ does not change.
