In order for 
to be as low as possible in statified sampling it is preferable
that each of the strata have as little homogeneity as possible.
True or false?
Homework Answers
The answer is TRUE since while stratfying we want to keep each strata as homogeneoous as possible

a) True or false: The simple rule for inventory turnover is that a low ration is preferable. b) True or false: An error in the ending inventory balance will cause an error in the calculation of cost of goods sold. c) True or false: Underwood had cost of goods sold of $8 million and its ending inventory was $2 million. Therefore, its days' sales in inventory equals 25 days. d) True or false: The choice of an inventory valuation method...

Using filterDesigner in MATLAB, design a second order low pass IIR Butterworth filter whose sampling frequency (Fs) is 1 kHz and cutoff frequency (Fc) is 10 Hz. Find the numerator and denominator coefficients. Write its transfer function H(z) = Y(z) / X(z). Write its difference function y(k). Draw (copy from Filter Designer) the magnitude response plot. Draw (copy from Filter Designer) the phase response plot. Draw (copy from Filter Designer) the impulse response plot.

- The required sample size for the interval estimation of the population mean μ can be computed if we specify the population standard deviation σ, the value of zα/2zα/2based on the confidence level 100(1 − α)% and the desired margin of error E. A) True B) False - In stratified random sampling, the population is first divided up into mutually exclusive and collectively exhaustive groups, called strata. Then simple random samples are drawn from each stratum, which are proportional to...
