Using The Practice of Statistics, 7th edition. This covers the second half of Unit 5B. • Determine if a statistic is an unbiased estimator of a population parameter. • Describe the relationship between sample size and the variability of an estimator.

In this video, we cover the Practice of Statistics 7th edition, unit 5B (day 1 of 2). Concepts covered include: • Distinguish between a parameter and a statistic. • Create a sampling distribution using all possible samples from a small population. • Use the sampling distribution of a statistic to evaluate a claim about a parameter.

This video lecture goes over how to construct a confidence interval for the population mean with the population standard deviation is known.

From The Practice of Statistics, 7th edition, Unit 5 Section A - Normal Distributions revisited. Learning Targets: • Calculate probabilities and percentiles involving normal random variables. • Find probabilities involving a sum, a difference, or another linear combination of independent, normal random variables.

Edwardsville High School Geometry 2022 (5.4). This video covers topics on equilateral and isosceles triangles. Specifically, the base angles theorem and its converse are covered with algebraic problems.

This video covers three topics: 1) How to simplify higher powers of the imaginary number, i 2) How to find a complex conjugate and divide complex numbers 3) How to plot a complex number and find its absolute value.

This video covers three topics of complex numbers: 1) How to reduce higher powers of the imaginary number, i. 2) How to find a complex conjugate and divide complex numbers. 3) How to plot complex numbers and find its absolute value.

This video shows examples of how to rationalize the denominator. Be sure to watch the video Simplifying Square Roots before watching this one!

How to simplify square roots into their exact value (no calculators)

This video shows two examples of graphing transformations to five points of accuracy. Included is one example with a quadratic function and one example with an absolute value function. Transformations include horizontal and vertical translations as well as vertical stretches and x-axis reflections.

This video demonstrates writing inequalities in interval notation.
