Confidence intervals | Unit 3 and 4 VCE Maths Methods
This video is aimed at students studying Unit 3 and 4 of VCE Mathematical Methods. This video is part of the topic on Statistical Inference.
This video looks at how to find and interpret confidence intervals. This includes
🔸 approximating the binomial distribution with the normal distribution for large samples
🔸 using the standard normal distribution to find a 95% confidence interval
🔸 changing the level of confidence, and the impact that this has on the width of the confidence interval
🔸 interpreting a confidence interval
🔸 the margin of error, and how to calculate the required sample size to ensure a specified margin of error
My class uses the Cambridge Senior Mathematics textbook for Units 3 and 4 Mathematical Methods for the Australian Curriculum / VCE. The content in this video is covered in Chapter 17 of this textbook.
Throughout the video I make use of the TI Nspire CAS CX II handheld.
