Ordered sampling without replacement
WebJan 28, 2024 · 1 I draw 4 tiles one by one from the bag as an ordered sample without replacement. Assume equally likely outcomes. Let C be the event that I get 2 Es, 1 A and 1 N. Compute P (c). So I started by taking P (14,4) which gave me 24,024. WebApr 23, 2024 · On the other hand, the variance of \(Y\) is smaller, by a factor of \(\frac{m - n}{m - 1}\), when the sampling is without replacement than with replacement. It certainly makes sense that the variance of \(Y\) should be smaller when sampling without replacement, since each selection reduces the variablility in the population that remains.
