To solve for $P(t_{41} > -0.189)$, we need to determine the probability that a value from the t-distribution with 41 degrees of freedom exceeds $-0.189$.

This is a right-tailed t-distribution problem, so we'll calculate the cumulative probability from the t-table or use statistical software to determine the corresponding probability.

Steps:

1. Since the t-distribution is symmetric around zero, $P(t_{41} > -0.189)$ can be calculated by looking at $P(t_{41} < -0.189)$ and subtracting from 1 (for the complement).
2. You would either consult a t-table or use a calculator to determine the cumulative probability for $t = -0.189$ and then compute the complement.

Given the value is small and negative, you expect the probability to be slightly above 0.5. Using statistical software:

$P(t_{41} > -0.189) \approx 0.5742$

Thus, the probability is approximately 0.5742 (rounded to four decimal places).

Tip: Always check the degrees of freedom carefully when using the t-distribution table.
