In the final years of Isabel II's reign, political, economic, and social unrest spread throughout Spain.

Factors Leading to Isabel II's Downfall

• The economic crisis led to rural and urban revolts.

Hypothesis Testing

Statistical Test Selection

1. If the population standard deviation is unknown and the sample size is less than 30: t-test

2. If the population standard deviation is known and the sample size is less than 30: t-test

7. Hypothesis test on population mean; n = 25; σ = 2.5: z-test

8. Hypothesis test on population mean; n = 50; s = 7.2: z-test

18. Test statistic for sample size above 30: z-test

19. Test statistic when population standard deviation is known: z-test

20. Test statistic when population standard deviation is unknown: t-test

21. When to use the t-test: I and II

24. Optimal sample size for z-test: Equal to or larger than 30

Hypotheses and Significance

Microtubules: Structure & Cellular Functions

Microtubules are dynamic polymers of tubulin proteins that form a crucial part of the eukaryotic cell's cytoskeleton, providing essential structure and shape. They are formed by the polymerization of a dimer of two globular proteins—alpha and beta tubulin—into protofilaments, which then associate laterally to form the hollow microtubule structure.

The microtubule cytoskeleton is extensively involved in the transport of materials within cells, a process carried out by motor proteins that move along the microtubule surface. They also constitute the internal structure of cilia and flagella, enabling cellular motility. Furthermore, microtubules provide platforms for intracellular transport and...

Python Regular Expressions: Pattern Matching Power

Regular expressions (regex) are a powerful tool for pattern matching and text manipulation. They allow you to search for patterns within strings, extract specific information, and perform text transformations. Python provides the re module for working with regular expressions.

Basic Regular Expression Components

1. Literals: Characters that match themselves.
2. Metacharacters: Special characters with special meanings, such as . (matches any character) and * (matches zero or more occurrences).
3. Character Classes: [...] matches any single character within the brackets.
4. Anchors: ^ matches the start of a string, $ matches the end of a string.
5. Quantifiers: * matches zero or more occurrences, + matches one or
