Why do we create t-statistics for hypothesis tests? Group of answer choices We create t-statistics for hypothesis tests to determine if there is a significant difference between sample data and the population parameter when the sample size is small and the population standard deviation is unknown. We create t-statistics for hypothesis tests to evaluate categorical data. We create t-statistics for hypothesis tests to measure the variability within a single sample. We create t-statistics for hypothesis tests to compare two large samples where the population standard deviation is known
