WebActivity Description. These weekly exercises provide the opportunity to understand and apply statistical methods and analysis. Unless otherwise stated, use 5% (.05) as your alpha level (cutoff for statistical significance). #1. For each example, state whether the one-sample, two-independent-sample, or related-samples t test is most appropriate. WebT.DIST.RT function. Returns the Student's t-distribution. T.INV function. Returns the t-value of the Student's t-distribution as a function of the probability and the degrees of freedom. T.INV.2T function. Returns the inverse of the Student's t-distribution. T.TEST function. Returns the probability associated with a Student's t-test. TREND function
WebOr maybe we should write this way. If I pick a random T-value, if I take a random T-statistic-- let me write it this way-- there's a 95% chance that a random T-statistic is going to be less than 2.262, and greater than negative 2.262. 95% percent chance. Now when we took this sample, we could also derive a random T-statistic from this. WebX and X̅ are standardised slightly differently. In both cases, the denominator is the square root of the variance, like so: For X, Z = (X-μ) / σ. For X̅, Z = (X̅ - μ) / (σ / √n) This fits with …
