## Theorems 
**124**

**CHAPTER 8**

**Theorem 8.1** 
**Statement:** In an obtuse-angled triangle, the square on the side opposite to the obtuse angle is equal to the sum of the squares on the sides containing the obtuse angle together with twice the rectangle contained by the sides, and the projection on it of the other.

**Given:** In ∆ABC, m∠C > 90°. Let us denote mAB = c, mAC = b and mAB = c. MAD = h is perpendicular from A to BC (produced) so that mCD = p is the projection of AC on BC.

1. Likert Scale

Developed by Rensis Likert in the 1930s, the Likert scale is a widely used method for measuring opinions and attitudes. It presents respondents with a series of statements and asks them to indicate their level of agreement or disagreement using a five-point scale:

  • Strongly Agree
  • Agree
  • Indifferent
  • Disagree
  • Strongly Disagree

Each response is assigned a numerical value, and an overall score is calculated by summing the values of all responses.

2. Probability Sampling

Probability sampling is

T-Tests

Understanding T-Distributions

True Statement: The larger the sample size, the more a t distribution resembles a normal curve.

Estimating Population Variance

When estimating the variance of a population from a sample, the sample variance cannot be used directly because it tends to be slightly too small—it underestimates the population variance.

T-Test vs. Z-Test

The difference between a t test for a single sample and a Z test for a single sample lies in how the variance of the known population
