Question

select the tcrit for the following situation: one tail, upper alpha = 0.10 n = 25

Explanation:

Step1: Determine degrees of freedom

Degrees of freedom ($df$) for a t - test is calculated as $df=n - 1$. Given $n = 25$, so $df=25 - 1=24$.

Step2: Identify the t - critical value

We are looking for a one - tailed (upper) critical value with $\alpha=0.10$ and $df = 24$. Using the t - distribution table or a statistical calculator, the t - critical value ($t_{crit}$) for a one - tailed test with $\alpha = 0.10$ and $df=24$ is approximately $1.7109$.

Answer:

1.7109
