a. Explanation Calculation: The frequency distribution of number of accounts in each stratum along with the standard deviation of account balances by stratum is provided. Consider a bound on the error of estimate of the population mean for saving account balances of B = $ 20 . Sample size: The sample size for estimating the population mean is, n = ( ∑ h = 1 H N h s h ) N 2 ( B 2 4 ) + ∑ h = 1 H N h s h 2 = [ ( 3 , 000 ) ( 80 ) + ( 600 ) ( 150 ) + ( 250 ) ( 220 ) + ( 100 ) ( 700 ) + ( 50 ) ( 3 , 000 ) ] 2 ( 4 , 000 ) 2 ( b. To determine Find the number to be sampled for each stratum using the Neyman allocation procedure.

Continuous Probability Distributions

Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could co…
