Find the value of the standard error of the mean in each of the following cases Suppose a random sample of size 50 is selected from a population with . (use the finite population correction factor if appropriate). a. The population size is infinite (to 2 decimals). b. The population size is N = 50,000 (to 2 decimals). c. The population size is N = 5000 (to 2 decimals). d. The population size is N = 500 (to 2 decimals). Hide Feedback Incorrect Check My Work

Answer 1

Standard Error in the mean • for finite population on = N-n VN-1 Colechon factor for infinite population or = - n is the sample sample size size and and is is the the population size. Now it n N population <0.05 means then in it is treated as an for finite population if infine V <0.05 then on = a Now for the population size infinite tere rag n= 50 - 1.27 (Upto 2 decinal) here n=50, N= 50,000 Ñ = 0.001 <0.05 Therefore our - 1.27 c) rue h = Therefore = 50 N = 5,000 0.01 40.05 on a = 1 5o = 1:27

1 = 50 , N = ৪০) * = ০ • 4 ) 0:55 = 500-50 - V50 --4 ও 5o = ইস ৩, 9496 12122 = ! 20 21 * 121

Therefore the answers are

a. 1.27

b. 1.27

c.1.27

d.1.21
