Use technology or a z-score table to answer the question.
The weights of logs in a wood pile are normally distributed with a mean of 17 pounds and a standard deviation of 3.4 pounds. The wood pile is composed of 325 logs.
How many of the logs will weigh 15 pounds or more?
I tried using the z-score formula 325-17
— =90.588 , this is not a possible answer since 90 is not on the z score table. Can you help me?
3.4
