The items their data sources and any relevant instructions for viewing the source data online appear at the end of this teacher version. In this guide we will go the whole process step by step. The first distribution is unimodal it has one mode roughly at 10 around which the observations are concentrated.
The second distribution is bimodal it has two modes roughly at 10 and 20 around which the observations are concentrated. Please type the population mean mu population standard deviation sigma and sample size n and provide details about the event you want to compute the probability for for the standard. If the population has a normal distribution the sampling distribution of x.
States and District of Columbia. Use a graphing calculator to create a box-and-whisker plot. Example 3 The weekly total points of Kevins fantasy football team are shown.
