WebOct 31, 2024 · Here are the steps you can follow when learning how to calculate test statistics using z-tests and t-tests: 1. Calculate the z-score. Assume you want to perform a z-test to determine whether the means of two populations are equal. The z-score calculation (z = (X - μ) / σ) requires three key values: Weba). Use StatCrunch and the Binomial Probability Calculator to find the probability that out of the class of 123 students, less than 100 of them are vaccinated. P(Less than 100 students out of 123 are vaccinated ) = Give your answer rounded to four decimal places. b) Use StatCrunch and the Binomial Probability Calculator to answer the question.
