question 11

Multiple Choice

• A) 0 C
• B) 37% of the minimum charge
• C) 68% of the maximum charge
• D) 68% of the minimum charge
• E) 96% of the maximum charge

A method used to approximate the distribution of a sum of independent random variables using the normal distribution, under certain conditions.

Continuity Correction

An adjustment made when approximating a discrete distribution with a continuous one, particularly relevant when making inferences about binomial distribution using normal approximation.

Null Hypothesis

A statement in statistics that suggests there is no significant difference or relationship between specified populations, any observed difference being due to sampling or experimental error.

Wilcoxon Signed Rank Test

A non-parametric statistical test used to compare two related samples to determine if their population mean ranks differ.
