Bass - Samples: The bass in Clear Lake have weights that are normally distributed with a mean of 2.3 pounds and a standard deviation of 0.8 pounds.

What percentage of all randomly caught groups of 3 bass should weigh between 2.0 and 2.6 pounds? Enter your answer as a percentage rounded to one decimal place.

I get so far but I can't determine the Z-score from the z-score table because it only goes up to 2 decimal places.
