The estimated probability $P(X \leq 2.55)$ is approximately 0.8453 based on the given CDF values.

Would you like further details on this interpolation process or any additional clarifications?

Here are 5 related questions to explore further:

1. How does linear interpolation work in estimating values between known points?
2. What is the significance of the cumulative distribution function (CDF)?
3. How would you compute $P(X > 2.55)$ using the CDF?
4. Can the interpolation method be used for other types of distributions?
5. How would you compute probabilities for continuous distributions without a table?

Tip: CDF values are useful because they give the probability that a random variable will take a value less than or equal to a given number.
