WebbA probability of 0 means that there is zero chance that the event will occur; a probability of 1 means that the event is certain to occur. Numbers between 0 and 1 quantify the uncertainty associated with the event. For example, the probability of a coin flip resulting in Heads (rather than Tails) would be 0.50. Webb13 apr. 2024 · Therefore, you need to find the distribution of the sample mean when n = 24 assuming the population is infinite (i.e., the "usual case"). You can then convert this distribution to the standard normal and look up the probability that the sample mean is located between 68.1 and 78.3. computer generated pick setWebbThis normal probability calculator for sampling distributions finds the probability that your sample mean lies within a specific range.
