WebTherefore, the probability that a random sample of 30 tubes will last an average of more than 2.5 years is approximately 100% - 3.07% = 96.93%. 4. False. The sampling distribution mean is equal to the population mean only if the sample is … WebInfinite Population Random Sample: a random sample of size n from an infinite population is a sample selected such that: 1. Each element selected comes from the same population 2. Each element is selected independently. Example: how would you select a random sample of customers arriving at a restaurant. Is this a finite population?

WebTo correct for the impact of this, the Finite Correction Factor can be used to adjust the variance of the sampling distribution. It is appropriate when more than 5% of the population is being sampled and the population has a known population size. There are cases when the population is known, and therefore the correction factor must be applied.
