Hypothesis Testing
• Single population Hypothesis testing

Answer 1

In the realm of statistics, estimation and hypothesis testing play pivotal roles in making informed decisions based on data analysis. Estimation allows us to make educated guesses about unknown parameters in a population, employing techniques such as point estimation, which provides a single best guess value, and interval estimation, which offers a range of plausible values, enhancing the accuracy of our assessments. Meanwhile, hypothesis testing serves as a powerful tool for validating assumptions or claims about a population. Through single population hypothesis testing, researchers can rigorously evaluate whether observed data supports a proposed hypothesis, leading to insights that drive further inquiry and understanding. Together, these concepts form the backbone of statistical inference, empowering us to draw conclusions from data with greater confidence.
