In this abbreviated lecture video, we will cover Sections 9.1 and 9.2 We will learn about confidence intervals, margins of error, critical values, and how to calculate necessary sample sizes.


In this video, you will watch an abbreviated lecture on Sections 7.3 and 7.1. We will discuss normal probability plots, the properties of normal distributions, and how to interpret the probabilities…


In this video, we will discuss how to calculate critical values (z sub alpha/2) using Statcrunch, TI 83/84 new and old operating systems, Excel, and other websites.


In this video, we will discuss what a Pvalue is and we also complete HW 4 question 46 starting at 9:35.

*Warning: The font gets blurry. I will rerecord this video, but I probably will not get it posted by Test 3. You can try maximizing the window size.


In this video, you will see an abbreviated review of the class lecture on Section 6.2 Binomial Probability Distributions. We will discuss how to determine whether we have a binomial experiment, how…


In this lecture video, we will discuss how to verify whether a distribution is a discrete probability distributions. We will also discuss how to calculate its mean and standard deviation.


In this abbreviated lecture, we will review the completed lecture notes from Sections 5.1 and 5.2.
