When the sample size is small and the population variance is unknown, the …

Question. Transcribed Image Text: Determine the t-value in each of the cases. Click the icon to view the table of areas under the t-distribution. WebThe t-distribution can be formed by taking many samples (strictly, all possible samples) of the same size from a normal population. For each sample, the same statistic, called the t-statistic, which we will learn more about later, is calculated. The relative frequency distribution of these t-statistics is the t-distribution. is a viral respiratory infection contagious
