WebOct 13, 2024 · How do you find the sampling interval of sample ratio? For example, if a sample of 15 houses is desired from a block containing 100, then N/n = 100/15 = 6.67. Choosing a sampling interval of k = 7 and allowing the sample size to be either 14 or 15 would then satisfy the requirement: (15 − 1) × 7 = 98<100 and 15 × 7 = 105 > 100. WebE = t α / 2 s n To determine the sample size, one first decides the confidence level and the half width of the interval one wants. Then we can find the sample size to yield an interval with that confidence level and with a half width not more than the specified one.
