Final Review

Concepts covered (+ Midterm)

• A hypothesis test is a statistical technique used to evaluate competing claims (null and alternative hypotheses) using data.
• We simulate a null distribution using our original data.
• We use our sample statistic and direction of the alternative hypothesis to calculate the p-value.
• We use the p-value to determine conclusions about the alternative hypotheses.
• Derivative Calculation: Computing the derivative of a given function.
• Integral Calculation: Solving an integral involving exponential and power functions.
• Vector and Matrix Transpose: Writing down the transpose of vectors and matrices.
• Matrix Dimensions: Determining the dimensions of matrices and the validity of matrix products.
• Matrix Multiplication: Performing matrix multiplication and understanding the resulting matrix dimensions.
