1. • • In summary, the key differences between the two mean formulas are µ vs. x̅ (mu vs. x bar symbols) and N vs. n. In each case, the former relates to the population, while the latter is for the sample mean formula. Summing up values and dividing by the number of items is consistent in both formulas.

   How do I use a mean calculator?

   • Enter each number into a separate field. You can input up to 50 numbers (new rows will appear as you fill out the fields). Remember that harmonic and geometric means can only use positive numbers; and The result will appear at the bottom of the mean calculator. Let x 1, x 2, ..., x n be a collection of numbers.

   What is the symbol for a sample mean?

   • The symbol for a sample mean is x̅, which you pronounce as X-bar. This type of average can be less useful because it finds only the typical height of a particular sample. However, if we collect a random sample, we can use x̅ to estimate µ. The process allows us to use the sample to estimate the properties of a population.

   How do you estimate a difference in a sample mean?

   • (a) The difference in sample means is an appropriate point estimate: ˉxn − ˉxs = 0.40. (b) Because the samples are independent and each sample mean is nearly normal, their difference is also nearly normal. (c) The standard error of the estimate can be estimated using Equation 5.3.6:
