Question

using the t - distribution table, find the critical value(s) for the t test for a left - tailed test with ( n = 16 ) and ( alpha=0.10 ). enter the answers separated by a comma if needed. critical value(s) =

Explanation:

Step1: Calculate degrees of freedom

Degrees of freedom \(df=n - 1\). Given \(n = 16\), so \(df=16-1 = 15\).

Step2: Locate critical value in t - table

For a left - tailed test with \(\alpha=0.10\) and \(df = 15\), looking at the t - distribution table. The value in the row \(df = 15\) and the column for one - tailed \(\alpha=0.10\) is \(-1.341\) (negative for left - tailed).

Answer:

\(-1.341\)
