This video will review confidence intervals and hypothesis testing for 2
sample mean and proportion problems.
|
|
|
This video will review confidence intervals and hypothesis testing for 1 sample mean and proportion problems. We will also calculate the sample size for mean and proportion problems.
|
|
|
In this video we will review how to write null and alternative hypotheses, create a 95% confidence interval, and perform the confidence interval hypothesis testing method with 1 sample.
|
|
|
In this problem we will review how to interpret confidence intervals.
|
|
|
In this video, we will go through a problem where we calculate a point estimate, check the assumptions, create and interpret a confidence interval for a population proportion.
|
|
|
In this video, I will cover Section 9.1 - 9.2 Estimating population proportions and population means. We will create point estimates and confidence intervals. We will also briefly calculate sample…

Creating Confidence Intervals for Mean Problems
|
|
|
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, we will create a confidence interval for 2 sample proportion problems. We will also interpret the conclusion.
